A B
2 6
2 6 G = 28
4 4 (sum of X-squared) åX2 = 128
0 4
T = 8 T = 20
SS = 8 SS = 4
Multiple choice
a) F(1,6) = 9.00, with a critical value of 5.99. Fail to reject H0 and conclude that the mean difference between treatments is not significant.
b) F(1,7) = 9.00, with a critical value of 5.59. Fail to reject H0 and conclude that the mean difference between treatments is not significant.
c) F(1,7) = 10.13, with a critical value of 9.00. Reject H0 and conclude that the mean difference between treatments is significant.
d) F(1,3) = 9.00, with a critical value of 10.13. Fail to reject H0 and conclude that the mean difference between treatments is not significant.
