The test statistic of z=2.58 is obtained when testing the claim that p=3/8.

a. Using a significance level of =0.10, find the criticalvalue(s).

b. Should we reject H0 or should we fail to reject H0?

Failtoreject H0. There isnot sufficient evidence to warrant rejection of the claim that p=3/8.

B.

Failtoreject H0. There is sufficient evidence to warrant rejection of the claim that p=3/8.

C.

Reject H0. There isnot sufficient evidence to warrant rejection of the claim that p=3/8.

D.

Reject H0. There is sufficient evidence to warrant rejection of the claim that p=3/8.
