Excel users should note that there may be rows with empty cells (representing missing data) that must be removed. Random samples from two normal populations produced the following statistics:
s21 = 350 n1 = 30 s22 = 700 n2 = 30
a. Can we infer at the 10% significance level that the two population variances differ?
b. Repeat part (a) changing the sample sizes to n1 = 15 and n2 = 15.
c. Describe what happens to the test statistic and the conclusion when the sample sizes decrease.
