A magazine looked at the success of CEOs with MBAs. Of the 1335 CEOs that responded, 37% said that they had earned an MBA. Complete parts a through c. a) Estimate the percentage of all CEOs they have earned an MBA. Use a 99% confidence interval. Check all of the conditions first. Is the Independence Assumption met? A. It cannot be determined. B. No OC. Yes Is the Randomization Condition met? O A. It cannot be determined. B. Yes C. No Is the 10% Condition met? A. No B. It cannot be determined. OC. Yes Is the Success/Failure Condition met? O A No Click to select your answer(s) A magazine looked at the success of CEOs with MBAs. Of the 1335 CEOs that responded, 37% said that they had earned an MBA. Complete parts a through C. Construct the 99% confidence interval. The interval is (%(%) (Round to one decimal place as needed.) b) Some believe that fewer contemporary CEOs are earning MBAs. Suppose we wished to conduct a hypothesis test to see if the fraction has fallen below the 43% mark. What does the confidence interval indicate? What does the confidence interval indicate? O A. Since 43% is greater than the upper limit of the interval, there is strong evidence that fewer than 43% of all CEOs have MBAs. B. Since 43% is in the interval, there is strong evidence that fewer than 43% of all CEOs have MBAS C. Since 43% is not in the interval, there is strona evidence that more than 43% of all CEOs have MBAS OD. Since 43% is in the interval, there is strong upper-tail than 43% of all CEOs have MBAS lower-tail c) What is the level of significance of this test? Exp two-tail The level of significance is The test is a(n) test based on a
