Description Details: The purpose of this assignment is to apply data distributions to discrete and continuous data and justify the selection of the distributions. For this assignment, you will use the "Random Variables" dataset. You will use SPSS to analyze the dataset and address the questions presented. Findings should be presented in a Word document along with the SPSS outputs. Part 1: Identify if the following random variables are discrete or continuous. Number of defected items in a shipment. Height of males (in mm) who attend Grand Canyon University. Yearly income among all people in the United States. Whether or not a high school graduate is accepted into a college. Time that it takes for a person to run a mile. The number of emergency hospital visits that each person had in the last 12 months. Part 2: Let X be a random variable of the outcome after rolling a six-sided die one time that is not fair. In fact, the die is designed to never result in a 1 or 6, while the other outcomes (i.e., 2, 3, 4, and 5) are equally probable. What are the individual probabilities for all possible values of X? What are the cumulative probabilities for all possible values of X? What is P[X = 3]= ? What is P[X ?3] = ? What is P[3 ?X ?5] = ? Part 3: The dataset provided consists of the following random variables: BMI: The body mass index of a random set of people. Distance: The distance (in feet) that a baseball player hit the ball. Height: The height of males (in mm). Income: The income (in dollars) of people in a large company. Pass: The outcome when taking an exam (1=Pass; 0=Fail). Wait Time: The time (in minutes) that it takes when waiting for the train. Answer each question below. Use SPSS as needed, and include the software outputs as part of the Word document you submit. What is a Q-Q plot? Given a set of realized values of a random variable, how can a Q-Q plot be used to assess the distribution of the random variable? Using histograms and Q-Q plots (except for binomial), match each random variable to one of the following distributions: Binomial (with N=1, P=0.7), Chi-square (with d.f.=20), Exponential, Lognormal, Normal, and Uniform. APA format is not required, but solid academic writing is expected. This assignment uses a grading rubric.

Description The Android client app you will you construct comes from the code pattern on this website: http://androidpala.com/android-httpurlconnection-post-get/ In this exercise, you will Modify an existing Android client application to send a service request to a java servlet. The java servlet (server) will reply back to the Android client with a response. Configure and run a java servlet (server) to run on your local machine. Configure the Java servlet. Download the latest Eclipse IDE (Oxygen) and create a new dynamic web project. Use the Java source file supplied by your instructor as the source code for your dynamic web project. Explore the code and note the implementations of the get and post methods. Launch the java servlet by using the built-in Tomcat Server that comes with the latest Eclipse Oxygen distribution. Take a screenshot of the Java servlet running. Note that the Eclipse Oxygen environment has a built-in web browser. In your screenshot, add a textbox and in the textbox, identify the service that is being performed by the servlet. Obtain the Android client app form your instructor. The name of this client app is “HttpExample.” This example already has the built-in code to send requests and receive responses from an external server. Take screenshots of the messages being displayed after clicking on the “GET METHOD” and “POST METHOD” buttons. In this step, you will modify your Android client to “consume” the service provided by the Java servlet running on your local host machine. Explore the code the Android app. Note how the button click events are used to send a request and receive a response. Using this code pattern, add a new button and a data entry textbox to send user data (from the data entry textbox) to the Java servlet when the button is clicked. Write the Java servlet response into the original Android app’s textbox. Take screenshots of your Android app before requesting the service and after receiving a response.

Description Write a program in PLP assembly that repeatedly reads the value of the switches (address: 0xf0100000) and displays a pattern on the LED array based on what switches. Each time the switch value is read, the pattern should be displayed regardless of whether the switch value has changed or not since the last time it was read. The table below indicates the pattern that should be displayed for each possible switch setting: switch hex binary 0 0x00000001 0b00000001 Turn all 8 LEDs on and then off 1 0x00000002 0b00000010 Turn all even numbered LEDs on and then off 2 0x00000004 0b00000100 Turn all odd numbered LEDs on and then off 3 0x00000008 0b00001000 Cycle through all 8 LEDs in order with only one LED on at a time (a marquee) Other Other Other All LEDs off

Description Simple Regression Analysis The purpose of this assignment is to apply simple regression concepts, interpret simple regression analysis models, and justify business predictions based upon the analysis. For this assignment, you will use the "Trucks" dataset. You will use SPSS to analyze the dataset and address the questions presented. Findings should be presented in a Word document along with the SPSS outputs. The business characteristics of n = 250 U.S. trucking and delivery companies for calendar year 2011 were recorded. Among the characteristics studied were the number of drivers and the number of trucks (power units) each company employed. Part 1: Given that the data consists of counts and range of counts is large, a natural log transformation is usually performed to improve the linear model results. Apply a natural log transform to both variables and then plot the Y = log(Trucks) vs. X = log(Drivers). Is there a linear relationship? Justify your answer by providing the SPSS output as an illustration. Part 2: Build a simple linear model by regressing Y on X and testing whether or not a relationship exists between the number of drivers and the number of trucks. Address the following questions in your written response: After fitting the model, plot the standardized residuals (on vertical axis) vs. the standardize predictions (on horizontal axis). Is there a pattern? How would you interpret the pattern or lack of pattern? After fitting the model, derive the normal probability plot and interpret what the plot means. What is the coefficient of determination, R2, of the model? How would you interpret the R2? What is the estimate of ?1? How would you interpret the estimate of ?1? Is the estimate of ?1 significantly different than 0? Assume an ? = 0.01. What is a 95% confidence interval for ?1? How would you interpret the 95% confidence interval for ?1? If a new trucking and delivery company with 4,900 drivers were to be formed, how many trucks would you expect the company would employ based on the model? APA format is not required, but solid academic writing is expected. This assignment uses a grading rubric. Please review the rubric prior to beginning the assignment to become familiar with the expectations for successful completion. Please include ... Discussion of the linear relationship and supporting SPSS output chart are complete and correct,Answers to simple regression analysis questions and supporting SPSS output charts are complete and accurate, and Writer is clearly in command of standard, written, academic English. Also please answer these 2 questions... QUESTION 1 - Suppose you wanted to understand the relationship between a customer's yearly income (X) and the number of movies (Y) the customer watched in a year. You then gather data on incomes and the number of movies watched in a year. The range of incomes in your data set is $5K to $150K. After fitting a simple linear model and performing all the appropriate diagnostics, the model showed that, on average, for every $10K in income, the customer watched 1.5 movies in the year. So, for example, if a customer earned 60K in a year, he or she would be expected to watch nine movies during the year. Now you want to apply this model to your very wealthy friend who will earn $1 million in the next year. Is this an appropriate application of your model? Why or why not? Provide specific examples to justify your opinion. QUESTION 2- If you regress daily high temperature (Y) on the amount of ice cream sales (X), you will notice that there is a strong positive correlation between the two. In other words, as daily ice cream sales increase, the daily high temperature increases. This implies that if we knew the amount of ice cream sales in a particular day, we could estimate, with a high level of accuracy, the high temperature in that day. Does this mean that if we wanted to increase the daily temperature, we need to sell more ice cream? Explain why or why not?

Description Assignment Instructions: Term Project - week 8 - (17%): You were just hired by an airline industry to create a database to record the various airlines and the pilots that work for them Discussions with the industry representatives focused on two initial entities, Airlines and Pilots; the following key points were agreed: 1. Each pilot is assigned a unique PilotID. 2. Each AirlineID is unique 3. Each pilot may work for one airline, each airline can have many pilots. 4. FName, LName, JobTitle and Salary describe each pilot (with the obvious meaning) 5. AirlineID, NPlanes, NRoutes, NPilots describe each airline (NPlanes number of planes, NRoutes number of routes, NPilots number of pilots) 6. No fields beyond those in the report are needed. The objective of this exercise is to demonstrate an understanding of some basic concepts covered in the course. The exercise is a straight forward application of those concepts – there are no “hidden” complexities – should you identify something in the key points or data that adds complexity, contact the instructor before submission – you may be over thinking the exercise.

Description CSE 230 Project 3: UART Palindrome Checker Learning Objectives: ? Create modular code and interface with unfamiliar modularized code The Task In this project, you will be writing a program that receives a string of characters via the UART, checks if this string is a palindrome, and then uses a print function to print either “Yes” or “No”. A palindrome sequence of characters (typically a word or phrase) that is the same both forwards and backwards. For this project, strings will be terminated using a period (‘.’). You may assume that a string will contain at least one character in addition to a period. You will not need to handle empty strings or strings with only a period. Your program should be able to handle multiple strings sent one after another or concatenated together. For example, the string: “abba. data.” should print “Yes” followed by “No” on the next line. Spaces should be ignored when checking for a palindrome and the palindrome should not be case sensitive. For example, “A nut for a jar of Tuna.” would be considered a palindrome. Print Function A skeleton PLP project file is available to download on Blackboard. The PLP project includes a second ASM file titled, project3_print.asm. This ASM file contains the print function used in this project. PLPTool concatenates all ASM files within a PLP project into a single location in memory (unless additional .org statements have been added to specify different location for code). No changes to project3_print.asm should be made. When called, depending on the value in register $a0, the following string will be displayed on the simulated UART device’s output. If $a0 contains a zero then “No” will be displayed and if $a0 contains a non-zero value (e.g. one) then “Yes” will be displayed. The print function is called using the following instruction: call project3_print To use the print function, your PLP program needs to initialize the stack pointer ($sp) before performing the function call (or any other operations involving the stack pointer). For this reason, the skeleton project file includes an initialization that sets the stack pointer to 0x10fffffc (the last address of RAM). Palindrome Checking Strategies There are two strategies I would recommend for saving your string in in memory and checking to see if it is a palindrome. The first would be to use only an array and keep a pointer (a register containing a memory address) for both the first element in the array (commonly referred to as a head pointer) and last element in the array (commonly referred to as a tail pointer). As you add elements to your array, update your tail pointer so that it moves to the new last element in the array. When you have reached the end of your string (a period has been received), you can perform your palindrome check comparing the characters your head and tail pointers point to and, if they point to the same character, move them both inwards towards the center of your array. If the pointers cross and all the characters were the same, your string was a palindrome. The second strategy would be to use an array, treated as a queue, and the stack. You can traverse the array from the start (the first character saved) to the end (the last character saved) while simultaneously popping characters off the stack. The queue will give you the string forwards and the stack will give you the string backwards. For both techniques I described above, keep in mind they are simpler if you perform some conditioning to the characters you receive before saving them. For example you don’t need to save spaces in your data structure(s) since they can be ignored and the comparisons are simpler if, when first receiving character, you convert them all to the same case (either all upper or all lower) before storing them. That way you won’t need to write logic that indicates things like “A” == “a” and “A” == “a”.
