In an election exit poll (N = 1,768), 898 respondents said they voted for Candidate A. Is Candidate A going to win the election (more than 50% of votes needed to win)? Use α = 0.1 for a hypothesis testing. Questions 33 to 38 are based on this example.

33. What’s the proportion of respondents in the poll voted for Candidate A?

34. What would be the H1 for the example?
A. The percentage of respondents in the poll voted for Candidate A is different from 50%.
B. The proportion of all voters in the election who would vote for Candidate A is more than 0.5.
C. The percentage of respondents in the poll voted for Candidate A is different from 50.8%.
D. The proportion of all voters in the election who would vote for Candidate A is more than 0.51.

35. What would be the Z critical value(s)?

36. What’s the standard error based on the sample information?

37. What is the Z obtained value?
