5a. Assume the following information for equal-sized samples, and make the appropriate t tests. a. Group1:x=25,s2 =27.8,n=150;Group2:x=23.7,s2 =27.8,n=150. b. Group1:x=25,s2 =27.8,n=150;Group2:x=29.5,s2 =27.8,n=150. c. Group1:x=125,s2 =92.6,n=400;Group2:x=121,s2 =92.6,n=400. d. Group1:x=125,s2 =92.6,n=400;Group2:x=131,s2 =92.6,n=400. e. Group1:x=11,s2 =15,n=30;Group2:x=11.5,s2 =15,n=30. f. Group1:x=11,s2 =15,n=30;Group2:x=13,s2 =15,n=30. 5b. Determine the probability of the t test result in (a) through (f) of Exercise 5a, and decide whether you would accept or reject the hypothesis of no difference between the two groups in each case.

b. Group1:x=25,s2 =27.8,n=150;Group2:x=29.5,s2 =27.8,n=150.
c. Group1:x=125,s2 =92.6,n=400;Group2:x=121,s2 =92.6,n=400.
d. Group1:x=125,s2 =92.6,n=400;Group2:x=131,s2 =92.6,n=400.
e. Group1:x=11,s2 =15,n=30;Group2:x=11.5,s2 =15,n=30.
