Is B a Good Choice on a Multiple-Choice Exam? Multiple-choice questions on Advanced Placement exams have five options: A, B, C, D, and E. A random sample of the correct choice on 400400 multiple-choice questions on a variety of AP exams1 shows that B was the most common correct choice, with 9090 of the 400400 questions having B as the answer. Does this provide evidence that B is more likely to be the correct choice than would be expected if all five options were equally likely? Show all details of the test. The data are available in APMultipleChoice.     Clearly state the null and alternative hypotheses.   Calculate the test statistic and pp-value. Round your answer for the test statistic to two decimal places, and your answer for the pp-value to three decimal places. test statistic ==  pp-value ==          Can we conclude that B is more likely to be the correct choice? Yes No
