What are the oul and sitemave hypotheses for the hypothesis teat? 16 14 Hy He (Type integers or decimals.

Since the P-value in greater than the significance level, tal to reject the null hypothesis. There is not sufficient evidence to support the chain that presidents tend to be taller than their opponents 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 om cm Round to one decimal place as needed.)
