E Click hero to view the t-Distribution Area in Right Tail.
(d) If the researcher decides to test this hypothesis at the a=0.05 level of significance, will the researcher reject the null hypothesis?
O A
The researcher will reject the null hypothesis since the P-value is not less than a
O B. The researcher will not reject the null hypothesis since the P-value is not less than a
O C. The researcher will reject the null hypothesis since the P-value is less than a.
O D. The researcher will not reject the null hypothesis since the P-value is less than a.
