Exercise 23

Avg difficulty 3.0

Working backwards, Part I. You are given the following hypotheses:

H0\displaystyle H_{0} :p=0.3\displaystyle:p=0.3 HA\displaystyle H_{A} :p≠0.3\displaystyle:p\neq 0.3

We know the sample size is 90. For what sample proportion would the p-value be equal to 0.05? Assume that all conditions necessary for inference are satisfied.
