b. If you were to use the alpha equals 0.04 level instead, would you reject the null hypothesis, fail to reject it, or do you not have enough information to know? ________

Solution

Already decided to reject the null hypothesis at alpha =0.05

This implies p <0.05

a) If sign =0.09 then p being less than 0.05 would necessarily be less than 0.09.

Hence reject the null hypothesis.

b) If alpha =0.04

we know that p <0.05

But specifically we must know whether p <0.04 or lies between 0.4 and 0.5

If p lies between 0.4 and 0.5 null will be accpted otherwise rejected

Hence do not have enough information to know
