We reject the null on an ANOVA test. We are interested in finding which groups" means are
significantly different with overall 95% confidence. Some sample statistics follow:
A
B
Sample Mean 3.67 5.78 4.89 4.32
Sample SD
0.87 1.48 0.78 1.27
Sample Size
69
Further MSW 1.2922. and some possible values for the Bonferroni multiplier
t (0.05/(2 2) -2.352. t (0.05/(2 3)} = 2.526, t [0.05/(2 4)} = 2.646, and t (0.05/(2 6)] = 2.812
Consider the overall 95% confidence intervals for the difference in means of two groups. (All
pairwise)
Which Cls suggest a true difference in means?
O group A vsS. group D
O group A vs, group C
O group B vs, group D
O group A vs. group B
O No Cl suggests a significant difference in means.
