Question

Consider a test for . If the P-value is such that you can reject H0 for = .01, can you always reject H0 for = .05? Explain your answer.

No. If the P-value lies below 0.01 you would reject at the 1% level of significance, but not at the 5% level.Yes. If the P-value lies below 0.01 you would reject at the 1% level of significance, but not at the 5% level.     No. If the P-value lies above 0.05 you would reject at the 1% level of significance and at the 5% level.Yes. If H0 is rejected at the 1% level it will always be rejected at the 5% level.

Explanation / Answer

Yes. If H0 is rejected at the 1% level it will always be rejected at the 5% level. The reason is that if p-value is less than 0.05, it is also less than 0.01
