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.) (c) Interpret the p-value for Step 3 of the hypothesis test.

5. A professor at Santa Fe College for STA2023 collected data from one of her classes in the Fall of 2017 to investigate the relationship between study time per week (average number of hours) and college GPA. The data for males in her class is given below: Study hours per week 5 6 10 12 13 15 21 25 GPA (grade point average) 2.7 3.0 3.1 3.3 3.2 3.4 3.8 3.6 (f)  Interpret R2 in the context of the problem with one sentence.

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.) (a) Which of the following best represents the hypothesis for Step 1 the hypothesis test?

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.) (a) What type of hypothesis test is this (think Step 1)?
