Please show your work step-by-step and explain why. 38. State whether you would reject or fail to reject the null hypothesis in each of the following cases (two-tailed): a) P=0.15; alpha=0.05 b) P=0.003; alpha=0.05 c) P=0.11; alpha=0.01 d) P=0.001 ; alpha = 0.001

Solution

NOte that we:

REJECT the null hypothesis when:   P < alpha
FAIL TO REJECT the null hypothesis when:    P >= alpha

Thus:

a. FAIL TO REJECT
B. REJECT
C. FAIL TO REJECT
D. FAIL TO REJECT [as it is equal, it falls on the second case]
