Question
Use the following data (alpha = .10) and the critical value method to find the critical difference in the mean vales required to reject the null hypothesis.
H0: 1 2 = 0 Ha: 1 2 < 0

Explanation / Answer
Consider the following formula:
(x1-x2)-z(12/n1 + 12/n2)1/2,<= 1 2 <=(x1-x2)+z(12/n1 + 12/n2)1/2
at 90 percent (as alpha is 0.1) z = 1.28
(51.2-53)-1.28*(522/32 + 612/33)1/2,<=1 2 <=(51.2-53)+1.28(522/32 + 612/33)1/2,
-19.774<= 1 2 <=16.1774
