The following data have the same sample means and variances that appeared in the preceding question but the sample size is increased to n = 10.
I II III n = 10 n = 10 n = 10 M = 1 M = 5 M = 6 N = 30
T = 10 T = 50 T = 60 G = 120
s² = 9.00 s² = 10.00 s² = 11.00 ∑X² = 890
SS = 81 SS = 90 SS = 99 Predict how the increase in sample size should affect the F-ratio for these data. Use an ANOVA to check your prediction.
Larger samples should the F-ratio.
