A2010 pew research foundation poll indicates that among 1099 college graduates, 33% watch the daily show. meanwhile, 22% of the 1110 people with a high school degree but no college degree in the poll watch the daily show. a 95% confidence interval for pcollege grad − phs, where p is the proportion of those who watch the daily show, is (0.07, 0.) verify that the 95% ci for pcollege grad − phs is (0.07, 0.15). show your computation.(b) conduct a hypothesis test to determine if the data provide strong evidence that there is a higher percentage of college graduates watch the daily show than those with a high school degree but no college degree. state the hypotheses. report the test statistic and the p-value.(c) determine if the following statements are true or false, and explain your reasoning if you identify the statement as false.i. 95% of random samples of 1,099 college graduates and 1,110 people with a high school degree but no college degree will yield differences in sample proportions between 7% and 15%.ii. a 90% confidence interval for pcollege grad − phs would be wider.iii. a 95% confidence interval for phs − pcollege grad is (−0.15, −0.07).
