Question
The test statistic of z= - 1.62 is obtained when testing the claim that p =4/7.

a. The critical value(s) is/are z=
(Round to two decimal places as needed. Use a comma to separate answers as needed.)
b. Choose the correct conclusion below.
O A. Fail to reject Ho. There is not sufficient evidence to warrant rejection of the cla
that p = 4/7.
O B. Reject Ho. There is not sufficient evidence to warrant rejection of the claim that p = 4/7.
OC. Reject Ho. There is sufficient evidence to warrant rejection of the claim that p = 4/7.
O D. Fail to reject Ho. There is sufficient evidence to warrant rejection of the claim that p = 4/7.
