Question

Test the hypothesis, using (a) the classical approach and then (b) the P-value approach. Be sure to verify the requirements of the test. H0: p=0.6 versus H1: p>0.6 n=200; x=140, α=0.05

(a) Choose the correct result of the hypothesis test for the classic approach below.

A.Do not reject the null hypothesis, because the test statistic is greater than the critical value.

B.Do not reject the null hypothesis, because the test statistic is less than the critical value.

C.Reject the null hypothesis, because the test statistic is less than the critical value.

D.Reject the null hypothesis, because the test statistic is greater than the critical value.

(b) Choose the correct result of the hypothesis test for the P-value approach below.

A.Reject the null hypothesis, because the P-value is less than α.

B.Reject the null hypothesis, because the P-value is greater than α.

C.Do not reject the null hypothesis, because the P-value is greater than α.

D.Do not reject the null hypothesis, because the P-value is less than α.

Answer #1

a)

The test statistic is given by:

Since this is a right-tailed test, so the critical value is given by:

Since the test statistic value is greater than the critical value, so we have sufficient evidence to reject H0.

Hence option D.

b)

The test statistic is given by:

Since this is a right-tailed test, so the p-value is given by:

Since p-value is less than 0.05, so we have sufficient evidence to reject the null hypothesis H0.

Hence option A.
