A presidential candidate's aide estimates that, among all college students, the proportion  p  who intend to vote in the upcoming election is at least  60% . If  142  out of a random sample of  245  college students expressed an intent to vote, can we reject the aide's estimate at the  0.1  level of significance? Perform a one-tailed test. Then fill in the table below. Carry your intermediate computations to at least three decimal places and round your answers as specified in the table. The null hypothesis: H0:   The alternative hypothesis: H1:   The type of test statistic: (Choose one)ZtChi squareF             The value of the test statistic: (Round to at least three decimal places.)   The critical value at the  0.1  level of significance: (Round to at least three decimal places.)   Can we reject the aide's estimate that the proportion of college students who intend to vote is at least  60% ?   Yes     No

2-Proportion Test

In a 2-proportion test, two separate proportions are measured at the same time, and their similarity is evaluated. It is also known as a 2-proportion z-test, and a comparison of two different proportions is done in this method.
