7)Assume a significance level of =0.05 and use the given information to complete parts(a) and(b) below.

Originalclaim: More than 48% of adults would erase all of their personal information online if they could. The hypothesis test results in aP-value of 0.1991.

a. State a conclusion about the null hypothesis.(Reject H0 or fail to reject H0.) Choose the correct answer below.

A.

Reject H0 because theP-value is lessthanorequalto .

B.

Failtoreject H0 because theP-value is lessthanorequalto .

C.

Reject H0 because theP-value is greaterthan .

D.
