A researcher wants to compare the variances of the heights (in inches) of four-year college basketball players with those of players in junior colleges. A random sample of 30 players from each type of school is selected, and the variances of the heights for each type are 2.43 and 3.15, respectively. At α = 0.10, is there a significant difference between the variances of the heights in the two types of schools?

For each of these problems, perform the following steps.

a. State the hypotheses and identify the claim.
b. Find the critical value(s).
c. Compute the test value.
d. Make the decision.
e. Summarize the results.
Use the traditional method of hypothesis testing unless otherwise specified.
