21. To create the following data we started with the same sample means and variances that appeared in problem 20 but increased the sample size to n = 25. M = 2 M = 3 M = 4 n = 25 n = 25 n = 25 %3D T = 50 T = 75 T = 100 %3D s2 = 2.67 s2 = 2.00 s2 = 1.33 %3D %3D a. Predict how the increase in sample size should affect the F-ratio for these data compared to the F-ratio in problem 20. Use an ANOVA to check your prediction. Note: Because the samples are all the same size, MS sample variances. b. Predict how the increase in sample size should affect the value of n² for these data compared to the n? in problem 10. Calculate n? to check your prediction. within is the average of the three
