a) Test an appropriate hypothesis and state your conclusion.

b) If you concluded there was adifference, estimate that difference with a 99% confidence interval and interpret your interval in context.

Let p1 be the proportion of voters planning to vote for the candidate in the firstpoll, and p2 be the proportion of voters planning to vote for the candidate in the new poll. Choose the correct null and alternative hypotheses below.

Determine the test statistic.

Find theP-value.
