5 In a hypothesis test for a proportion, the null hypothesis is HO: p = 0.7 and the alternative hypothesis is H1: P = 0.7 with a = 0.05. Then we reject HO if the test statistic Z is 15 (5 Points) between -1.64 and 1.64 and cannot reject H0 otherwise greater than 1.64 or less than-1.64 and cannot reject H0 otherwise between -1.96 and 1.96 and cannot reject HO otherwise greater than 1.96 or less than-1.96 and cannot reject...
