Use the following information to answer the question. A pescatarian is a person who eats fish and seafood but no other animal. An event planner does some research and finds that approximately 2.75% of the people in the area where a large event is to be held are pescatarian. Treat the 250 gueststs expected at the event as a simple random sample from the local population of about 150,000. On average, what proportion of the guests would be expected to be pescatarian, give or take how many? Round to the nearest whole person.

Assignment #3 Sampling Distributions 1.      Forest type 1 has an average diameter of 35 cm and a standard deviation of 6 cm. Forest type 2 has an average diameter of 25 cm and a standard deviation of 5 cm. The distribution of the diameters is normal in both types. 1.      What is the probability that a sample mean will be greater than 36 cm from type 1 if 20 trees are measured? 2.      What is the probability that a sample variance is less than 19 cm2 from type 1 if 20 trees are measured? 3.      Find the probability that the sample mean computed from 20 measurements from type 1 will exceed the sample mean computed from 25 measurements from type 2 by at least 11 cm.   4.      Find the probability that the ratio of sample variances (S12/S22) computed from 10 measurements from type 1 (S12) and 8 measurements from type 2 (S22) will exceed 5.4.

  Select a grade level 1-5. Visit four websites that contain math lesson plans focused on operations and algebraic thinking. Using the four sample lesson plans, the Common Core State Standards for Mathematical, and the “Class Profile” as resources, design an original lesson using the “COE Lesson Plan Template.” Be sure your original lesson plan includes a research-based instructional strategy from the assigned readings as well as promotes one or more of the Standards for Mathematical Practice from the Common Core State Standards for Mathematics. Using the “Class Profile,” include 2-3 differentiation strategies in your lesson plan based on the needs of the students.  Cite the websites that you used to develop this lesson plan. While APA style format is not required for the body of this assignment, solid academic writing is expected, and in-text citations and references should be presented using APA documentation guidelines, which can be found in the APA Style Guide, located in the Student Success Center. This assignment uses a rubric. Review the rubric prior to beginning the assignment to become familiar with the expectations for successful completion. You are required to submit this assignment to Turnitin.

100. What is meant by the term “90% confident” when constructing a confidence interval for a mean? a. If we took repeated samples, approximately 90% of the samples would produce the same confidence interval. b. If we took repeated samples, approximately 90% of the confidence intervals calculated from those samples would contain the sample mean. c. If we took repeated samples, approximately 90% of the confidence intervals calculated from those samples would contain the true value of the population mean. d. If we took repeated samples, the sample mean would equal the population mean in approximately 90% of the samples. 106. Suppose that a committee is studying whether or not there is waste of time in our judicial system. It is interested in the mean amount of time individuals waste at the courthouse waiting to be called for jury duty. The committee randomly surveyed 81 people who recently served as jurors. The sample mean wait time was eight hours with a sample standard deviation of four hours. a. i. x ¯ = __________ ii. sx = __________ iii. n = __________ iv. n – 1 = __________ b. Define the random variables X and X ¯ in words. c. Which distribution should you use for this problem? Explain your choice. d. Construct a 95% confidence interval for the population mean time wasted. i. State the confidence interval. iii. Calculate the error bound. e. Explain in a complete sentence what the confidence interval means. 110. Forbes magazine published data on the best small firms in 2012. These were firms that had been publicly traded for at least a year, have a stock price of at least $5 per share, and have reported annual revenue between $5 million and $1 billion.
