Questiоns 13а, 13b, 13c аsk аbоut different parts оf a hypothesis test from the same research study, presented below. Multiple-choice questions on Advanced Placement exams have five options: A, B, C, D, and E. A random sample of the correct choice on 400 multiple-choice questions on a variety of AP exams shows that B was the most common correct choice. 90 of the 400 (90/400= 0.225) questions in the sample had B as the answer. We are interested to know if this sample provides evidence that B is more likely to be the correct choice than would be expected if all five options were equally likely. That is, we are testing vs where = the true proportion of all AP questions that have B as the answer. Determine the p-value of the test and give the conclusion of the test at the alpha = 0.05 level. Choose only one option below. Please pay careful attention to the answer choices; there are subtle differences in each option and there is only one correct answer.
