For this problem you must state the null and alternative hypothesis, the critical value/s and/ or the rejection graph, the test statistic, a sentence describing your results, and the p-value of rejection.

4. Suppose prior election in a certain state indicated that it is necessary for a candidate governor to receive at least 80% of the vote to be elected. The incumbent governor is interested in assessing his or her chances of returning to office and plans to conduct a survey of 2,000 registered voters in the state. The incumbent governor is interested only in less than 80%. From the survey, 1,560 registered voters said they planned to vote for the incumbent governor. At the 9% significance level, can the incumbent governor be assured of reelection?

1.) For each problem, state the null and alternative hypotheses, calculate the critical value(s) of the statistic by which you would reject the null hypothesis and state whether or not you would reject the null hypothesis for a level α specified by each problem. If the hypothesis test requires an unpaired t-test, then you may assume that the population variances are equal. Then calculate the appropriate statistic value by hand and use the appropriate probability table to obtain the exact...
