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.

Question 2

Using the .01 level of significance means that, in the long run,
 
  A) a Type I error occurs 1 time in 20.
  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.
