# Hypothesis testing : Z test for proportion

A presidential candidate's aide estimates that, among all college students, the proportion p who intend to vote in the upcoming election is at most 65%. If 196 out of a random sample of 270 college students expressed an intent to vote, can the aide's estimate be rejected at the 0.1 level of significance?

What is the null hypothesis?

What is the alternative hypothesis?

What is the type of test statistic? (Z, t, F, chi squared)

What is the value of the test statistic? (Round to at least three decimal places)

What is the critical value at the 0.1 level of significance? (Round to at least three decimal places)

Can you reject the aide's estimate that the proportion of college students who intend to vote is at most 65%?
