It examines how many people would answer yes when asked whether they ever feel depressed. The percentage who answer “yes” answers is 25% from a sample of 100 randomly asked people. The researchers want to know if the percentage is greater than 20%. To that end they set the null hypothesis to H0: p0 = 20%. From what percentage can the null hypothesis be rejected when a significance level is used of 2.5%?
