Suppose we want to estimate the proportion of college students who will travel overseas this summer. We randomly sample 40 college students. Assume the true proportion of all college students who will travel overseas is p=0.3p = 0.3. Based on this information, what can we say about the shape of the distribution of sample proportions?

Questions 13a, 13b, 13c ask about different parts of 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.
