The test statistic of z= -3.24 is obtained when testing the claim that p=3/8. a. Using a significance level of a=0.01, find the critical value(s).
b. Should we reject H0 or should we fail to reject H0?

a. The critical value(s) is/are z=
b. Choose the correct conclusion below.
A. Fail to reject H0. There is sufficient evidence to warrant rejection of the claim that p=3/8.
B. Reject H0. There is not sufficient evidence to warrant rejection of the claim that p=3/8
C. Reject H0. There is sufficient evidence to warrant rejection of the claim that p=3/8.
D. Fail to reject H0. There is not sufficient evidence to warrant rejection of the claim that p=3/8.
