Question: The following table summarizes data on body weight gain both for a sample of animals given a dose of steroid and for a sample of control animals. According to prior studies the population variances can be considered the same.

Problem: Steroid
36.95 32.27
36.75 34.78
38.92 32.85
35.27 32.52
38.46 35.26
39.42 32.86
37.77 33.29
30.44 32.51
  1. Do the data suggest that the average weight gain for the control group exceeds that of the steroid group? Use a significance level of .05.
  2. Test to see if the claim of equal variances is correct, using a significance level of 0.1.
