(All Steps) Consider the following hypothesis test: H_0:p=0.20 , H_A:p≠ 0.20 , A sample of 400 provided a sample proportion p=0.175 Compute the value of


Question: Consider the following hypothesis test:

\(\begin{aligned} & {{H}_{0}}:p=0.20 \\ & {{H}_{A}}:p\ne 0.20 \\ \end{aligned}\)

A sample of 400 provided a sample proportion \(p=0.175\)

  1. Compute the value of the test statics

c. At \(\alpha = .05\) what is your conclusion?

d. What is the rejection rule using the critical value? What is your conclusion?
