A fellow-student is testing H0:=42

against Ha:>42, at the 5% significance level. He gets t=1.812 and a right-tailed P-value of 0.043. He decides to reject H0. In reviewing his work, you realize his alternative hypothesis should have been Ha:42. How does this affect his P-value and the conclusion of his test?

______He needs to divide his P-value by 2. He should still reject H0. ______He needs to divide his P-value by 2. He should fail to reject H0. ______He needs to multiply his P-value by 2. Heshould still reject H0. ______He needs to multiply his P-value by 2. He should fail to reject H0. ______His P-value won't change. He should still reject H0. ______His P-value won't change. He should fail to reject H0.
