AReject H0 if t 1684 BReject H0 if t 2021 CReject H0 if t

A.Reject H₀ if t > 1.684.

B.Reject H₀ if t < 2.021.

C.Reject H₀ if t > 2.021.

D.Reject H₀ if t > 2.021 or t < -2.021.

E.Reject H₀ if t > 1.684 or t < -1.684.

Solution

It depends on the alternative hypothesis, we take alternative hypothesis not equal to the correct option is then

D.Reject H₀ if t > 2.021 or t < -2.021.

Since critical value is 2.021
