There is not sufficient evidence to support the claim that presidents tend to be Since the P-value is taller than their opponents. b. Construct the confidence interval that could be used for the hypothesis test described in part (a) What feature of the confidence interval leads to the same conclusion reached in part (a)? The confidence interval is cm
