1. A "random survey" was conducted of 3274 people of the "microprocessor generation" (people born since 1971, the year the microprocessor were invented). It was reported that 48% of those individuals surveyed stated that if they had $2000 to spend, they would use it for computer equipment. Also, 66% of those surveyed considered themselves relatively savvy computer users.   (Source: San Jose Mercury News)   a. Do you consider the sample size large enough for a study of this type? Why or why not?   b. Based on your "gut feeling," do you believe the percents accurately reflect the U.S. population for those individuals born since 1971? If not, do you think the percents of the population are actually higher or lower than the sample statistics? Why?   Additional information: The survey was reported by Intel Corporation of individuals who visited the Los Angeles Convention Center to see the Smithsonian Institute's road show called "America's Smithsonian."   c. With this additional information, do you feel that all demographic and ethnic groups were equally represented at the event? Why or why not?   d. With the additional information, comment on how accurately you think the sample statistics reflect the population parameters.       2. Twenty-five randomly selected students were asked the number of movies they watched the previous week. The results are as follows:   # of movies Frequency Relative Frequency Cumulative Relative Frequency   0 5   1 9   2 6   3 4   4 1   Table 2.1   a. Find the sample mean x   b. Find the sample standard deviation, s   c. Construct a histogram of the data.   d. Complete the columns of the chart.   e. Find the first quartile.   f. Find the median.   g. Find the third quartile.

. Angelina's Italian Restaurant has collected data about customer sauce orders. It calculated that P(pesto) = 0.42, P(alfredo) = 0.86, and P(pesto or alfredo) = 0.93. Determine the P(pesto and alfredo). 0.35 0.07 0.51 0.23       2. ??Brad is testing whether school is more enjoyable when students are making high grades. He asked 110 students if they enjoyed school and whether their GPA was above or below 3.5. He found that 38 of the 45 students with a GPA above 3.5 reported that they enjoyed school, and 7 of the 65 students with a GPA below 3.5 reported that they enjoyed school. What is the probability that a student with a GPA below 3.5 does not enjoy school? 89% 92% 85% 75%       3. In a study of 225 adults, the mean heart rate was 72 beats per minute. Assume the population of heart rates is known to be approximately normal with a standard deviation of 10 beats per minute. What is the 90% confidence interval for the mean beats per minute? 70.7 – 73.3 70.9 – 73.1 70.7 – 73.1 70.9 – 73.3       4.A mechanic gives a survey to all of his customers asking them to rate the quality of the service they received. He then keeps track of how many customers return to the shop for additional services during the next six months. Last year, the results showed that of the customers who reported high quality service, 20% returned for additional services. What conclusion can be drawn from this study? Some customers who rate their service as high quality return for additional services. Most customers who rate their service as high quality return for additional services. High quality services cause customers to return for additional services. Customers who will return for additional services report a high quality of service.       5. ??Amy is playing a board game and rolls two number cubes. Let A = {the sum of the number cubes is odd}, and let B = {the sum of the number cubes is divisible by 3}. List the outcomes in A ? B. {3, 6, 9, 12} {1, 3, 5, 7, 9, 11} {3, 5, 6, 7, 9, 11, 12} {2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12}               8. Lars wants to know if warming up will help runners sprint faster. Twenty-four track and field athletes volunteered to participate in his study. He randomly assigns 12 athletes to warm-up for 10 minutes. All 24 participants sprint the same distance. He calculates the mean for each group and determines that the mean for the warm-up group was 7.8 seconds and the mean for the other group was 9.8 seconds. To test the difference of means, he re-randomized the data 54 times and the differences are plotted in the dot plot below. What can Lars conclude from her study??? The difference in the means is significant because a difference of 2 is very likely. The difference in the means is significant because a difference of 2 is not very likely. The difference in the means is not significant because a difference of 2 is not very likely. The difference in the means is not significant because a difference of 2 is very likely.   7.Hunter wants to prove to his parents that playing computer games while he studies for tests will help him get better grades. He decides to ask 30 of his friends if they play computer games while they study for their tests and what their grades are. He finds that his friends who have high grades also play computer games while they do their homework. He tells his parents that he has proven that playing games while studying for tests will cause his grades to improve. What mistake has Hunter made? He did not use a random sample, and he tried to show cause and effect with an experiment. He did not use a random sample, and he tried to show cause and effect with an observational study. He did not separate his friends into different groups, and he didn't apply a treatment. He did not separate his friends into different groups, and he used a survey to collect data.   8. A survey of 1,200 men and women asked, "Do you earn over $75,000 per year?" The table below shows the responses for males and females:?   Male Female Total Income over $75,000 585 485 1,070 Income below $75,000 65 65 130 Total 650 550 1200     Based on these data, are "being female" and "earning over $75,000" independent events? No, P(being female | the person earns over $75,000) = P(being female) No, P(being female | the person earns over $75,000) ? P(being female) Yes, P(being female | the person earns over $75,000) = P(being female) Yes, P(being female | the person earns over $75,000) ? P(being female)     9.

2. Two roads intersect at 34 degrees. Two cars leave the intersection on diff roads at speeds of 80km/h and 100 km/h. After 2h, a traffic helicopter that is above and between the 2 cars takes readings on them. The angle of depression to the slower car is 20 degrees, and the straight line distance from the helicopter and the car is 100 km. Assume that both cars are traveling at constant speed. a) Calculate the straight line distance, to nearest km from helicopter to faster car. b) Determine the altitude of helicoptor to nearest km.

Im great.    Okay, Let me know if you are cable of doing the assignment   Here the attached documents. You will need to do A,B,C,D,E for the Mossaic Tiles, LTD Case Problem.  Problems 55&57 on the additional help sheet  May help you with the set up of the linear equation and the constraints  If you get these correct without the answer key it should help.  The set up is the main thing to get correct so that you can use solver or QM. Below are the requirements for the assignments    Assignment 1. Linear Programming Case Study Your instructor will assign a linear programming project for this assignment according to the following specifications. It will be a problem with at least three (3) constraints and at least two (2) decision variables. The problem will be bounded and feasible. It will also have a single optimum solution (in other words, it won’t have alternate optimal solutions). The problem will also include a component that involves sensitivity analysis and the use of the shadow price. You will be turning in two (2) deliverables, a short writeup of the project and the spreadsheet showing your work. Writeup. Your writeup should introduce your solution to the project by describing the problem. Correctly identify what type of problem this is. For example, you should note if the problem is a maximization or minimization problem, as well as identify the resources that constrain the solution. Identify each variable and explain the criteria involved in setting up the model. This should be encapsulated in one (1) or two (2) succinct paragraphs. After the introductory paragraph, write out the L.P. model for the problem. Include the objective function and all constraints, including any non-negativity constraints. Then, you should present the optimal solution, based on your work in Excel. Explain what the results mean. Finally, write a paragraph addressing the part of the problem pertaining to sensitivity analysis and shadow price. Excel. As previously noted, please set up your problem in Excel and find the solution using Solver. Clearly label the cells in your spreadsheet. You will turn in the entire spreadsheet, showing the setup of the model, and the results.
