The publisher of Golf Illustrated has found through past experience that 75% of its subscribers renew their subscriptions. The publisher selects a random sampleof 200 subscribers and finds that 139 plan to renew their subscriptions.

Use a hypothesis testingprocedure and alpha = 0.05. Be sure to clearly state the null and alternate hypothesis using proper notation.
