4.

A national television network took an exit poll of 1370 voters after each had cast a vote in a state gubernatorial election. Of them, 630 said they voted for the Democratic candidate and 740 said they voted for the Republican candidate. Treating the sample as a random sample from the population of all voters, a 95% confidence interval for the proportion of all voters voting for the Republican candidate was (0.514,0.567). Suppose the same proportions resulted from n = 137 (instead of 1370), with counts of 63 and 74, and that there are only two candidates. Complete parts a and b below. a. Does a 95% confidence interval using the smaller sample size allow you to predict the winner? Explain. The 95% confidence interval for the proportion of all voters voting for the Republican candidate is (). Now a 95% confidence interval interval (Round to three decimal places as needed.) allow you to predict the winner, since this
