... So, standard error of p bar = sqrt (P*Q/n) = sqrt (0.75*0.25/50) = 0.0612 Z – value = p bar – P / standard error = 0.7 – 0.75 / 0.0612 = - 0.8165 The critical z value = - 1.64 So, the z value lies in the acceptance region, so we do not reject the null hypothesis. So, there is not enough evidence to ...

Using a Bonferroni inequality, it has been shown that to ensure an overall significance level equal to or smaller than alpha for all k desired tests, a significance of alpha/k should be used (Miller ...
