Accоrding tо а reputаble mаgazine, the drоpout rate for all college students with loans is 30%. Suppose that 63 out of 200 random college students with loans drop out. We would like to test whether the dropout rate is different from 30% using the significance level of 0.01. (1) Calculate the test statistic and p-value (the Normal distribution table is shown below) for this hypothesis test (show your work). (6 pts) (2) Determine whether we should reject or not to reject the hypothesis (state the reason to support your answer). (4 pts) (3) Then state the conclusion of the hypothesis test. (4 pts) Assume that all required conditions are met.
