Identify a population to study. Identify the sampling method to be utilized and why. How is the sample to be collected? (survey, in person questions, email, facebook, etc). Identify the Hypotheses to be tested. Identify the type of test (one population, two population). Identify the Parameter and Statistic to be tested (mean, proportion, etc). Collect Data on n ≥ 30, state sample size:_____________ Follow the steps to Hypotheses testing, analyze your data using statistical software. Include any applicable graphs and descriptive statistics. Summarize your findings in a paragraph. age sex rate_diabetes 15-44 Overall 4 45-64 Overall 32 65-74 Overall 99 75+ Overall 248 15-44 Males 5 15-44 Females 3 45-64 Males 37 45-64 Females 28 65-74 Males 120

In Problems 9-12, conduct each test at the a= 0.05 level of significance by determining (a) the null and alternative hypotheses, (b) the test statistic, (c) the critical value, and (d) the P-value. Assume that the samples were obtained independently using simple random sampling.

You are the operations manager for an airline and you are considering a higher fare level for passengers in aisle seats. How many randomly selected air passengers must you survey? Assume that you want to be 95% confident that the sample percentage is within 5.5 percentage points of the true population percentage. Complete parts (a) and (b) below. a. Assume that nothing is known about the percentage of passengers who prefer aisle seats. (Round up to the nearest integer.) b. Assume that a prior survey suggests that about 33% of air passengers prefer an aisle seat. n3= (Round up to the nearest integer.)
