Thep-value for the test of the equality of the means of all populations is calculated to be0.6406. Suppose you plan to increase the sample sizes for all groups but keep them all equal. However, when you do this, the sum of squares within samples and the sum of squares between samples (magically) remain the same. What are the smallest sample sizes for groups that would make this result significant at the5%significance level?

Answer #1

solution

total df=49

number of groups =4+1=5

number of points = df+1

=49+1

=50

group sample size=no of points /number ofgroups

=50/5

=10
