9.  A 2016 headline read “FSU is the Most Sleep Deprived University.”  Do students sleep more at UF or FSU?  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: University of Florida (UF):       n=207       sample mean = 7.59       s = 1.65 Florida State University (FSU):       n=164       sample mean = 7.13       s = 1.61 Construct and interpret a 95% confidence interval for the difference in the population mean number of hours students sleep per night at UF and FSU. (a) What is the t-value for the 95% confidence interval?

8.  A 2024 headline in the New York Daily News stated “Majority of Catholics Support Abortion Rights.”  This headline was based on a 2023 study by Pew research which stated that more than 60% of adult American Catholics favored legal abortion.  Spcifically 381 out of 624 randomly selected adult American Catholics said that they favored legal abortion.  Construct and interpret a 95% confidence interval for the population proportion of adult American Catholics who favor legal abortion. (d) What is the lower bound of the 95% confidence interval?

(e) What is the conclusion in the context of the problem for Step 5 of the hypothesis test?

7.  A 2024 headline in the New York Daily News stated “Majority of Catholics Support Abortion Rights.”  This headline was based on a 2023 study by Pew research which stated that more than 60% of adult American Catholics favored legal abortion.  Spcifically 381 out of 624 randomly selected adult American Catholics said that they favored legal abortion.  Conduct a test of hypothesis to determine if this data (381 out of 624) shows that the population proportion of adult American Catholics who favor legal abortion is more than 0.60. (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?
