9.  Do students sleep more in Pennsylvania or in California? A study was designed to estimate the difference in the number of hours students sleep per night and the summary statistics for the following two universities is given below: Penn State University:       n=190       sample mean = 7.17       s = 1.95 University of California, Davis:       n=173       sample mean = 6.83       s = 1.71 Does the data show that the mean number of hours that Penn State University students sleep per night is significantly different from the mean number of hours that University of California, Davis students sleep per night?  (While answering the following sub-parts of this question, you will be including the null and alternative hypothesis, the test statistic, the p-value (a visualization and an interpretation), your statistical decision, and your conclusion in the context of the problem.) (d) What is the correct statistical decision for Step 4 of the hypothesis test?

7.  Time magazine reported in a 2004 survey of 507 randomly selected adult American Catholics, that 279 answered yes to the question “Do you favor allowing women to be priests?”  Conduct a test of hypothesis to determine if this data (279 out of 507) shows that the population proportion of adult American Catholics who favor allowing women to be priests is more than 0.50. (While answering the following sub-parts of this question, you will be including the null and alternative hypothesis, the test statistic, the p-value (a visualization and an interpretation), your statistical decision, and your conclusion in the context of the problem.) (c) Interpret the p-value for Step 3 of the hypothesis test.

6.  The following are Blood Alcohol Contents (BAC’s) of a random sample of drivers arrested last New Years Eve in Gainesville by the Florida Highway Patrol (FHP):  0.09, 0.11, 0.14, 0.25, 0.09, 0.20, 0.10.  Assume that the population of BAC’s is normally distributed.  Find and interpret a 95% confidence interval for the mean BAC of drivers arrested on New Year’s Eve in Gainesville by the FHP.   (d) What sample statistic in the confidence interval estimates the population mean?

3. The University of South Florida’s Tobacco Research and Intervention Program reported that only 5% of the nation’s cigarette smokers ever enter into a treatment program to help them quit smoking.  To investigate smoking cessation on their own campus, university researchers took a random sample of 200 smokers who participated in the university’s treatment program.  Upon completion of the treatment program, participants were asked if they had quit smoking and answered with a “yes” or “no” response.  A random variable will be used to measure the number of participants who answered yes.  This random variable is best modeled after what type of distribution?  Explain your answer.
