What sample size would be needed to construct a margin of error of 2% with 95% confidence? Use the prior estimate of p = 0.2 for this estimate.\fQuestion 33 1 pts Part 5: The value of your test statistic is: Question 34 1 pts Part 6: The P-value of your test is: Question 35 1 pts Part 7: What is your conclusion? 0 There is sufcient evidence to conclude that graduates from the top ten business programs perform the same as other investment managers. 0 There is sufcient evidence to conclude that graduates from the top ten business programs perform better than other investment managers. 0 There is insufcient evidence to conclude that graduates from the top ten business programs perform better than other investment managers 0 There is insufcient evidence to conclude that graduates from the top ten business programs perform the same as other investment managersStep by Step Solution
