What is the procedure/formula for solving this problem?
Post Merge: 6 years ago

An investor wants to compare the risks associated with two different stocks. One way to measure the risk of a given stock is to measure the variation in the stock’s daily price changes.

In an effort to test the claim that the variance in the daily stock price changes for stock 1 is different from the variance in the daily stock price changes for stock 2, the investor obtains a random sample of 21 daily price changes for stock 1 and 21 daily price changes for stock 2.

The summary statistics associated with these samples are: n1 = 21, s1 = .849, n2 = 21, s2 = .529. 

If you follow Bluman's advice and place the larger variance in the numerator, what is the test value associated with this test of hypothesis?

F = .849^2/.529^2 =2.576.

F = .848^2/.529^2 = 2.570
