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. 

11. In 2004, a random sample of 46 coyotes in a region of northern Minnesota showed the average age to be 2.05 years with a standard deviation of 0.82 years.  However, it is thought that the overall population mean age of coyotes is 1.75 years.  Test the hypothesis that coyotes in this region of northern Minnesota live longer than the average of 1.75 years.  (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.) (b)  What is the value of the test statistic in Step 2 of the hypothesis test?
