Given four populations with equal means and equal variances, an F distribution for situations with samples of 10 scores each could be created by

A) applying the t test formula to each pair of samples, squaring the results to obtain F ratios, then repeating this process a large number of times.
B) applying the analysis of variance formula to a set of four samples (one from each of the four populations) of 10 scores each, determining the degrees of freedom, and repeating this process a large number of times.
C) taking 10 samples from each of the four populations, figuring the F ratio, and repeating this process a large number of times.
D) taking samples of 10 scores from each of the four populations, figuring an F ratio for each set of samples, and repeating this process a large number of times.

B) a Type I error occurs 1 time in 100.
C) a Type II error occurs 1 time in 20.
D) a Type II error occurs 1 time in 100.
