price changes for stock 1 and 21 daily price changes for stock 2.
The summary statistics associated with these samples are: n
= 21, s
= .725, n
= 21, s
If you compute the test value by placing the larger variance in the numerator, at the .05 level of
significance, would you conclude that the risks associated with these two stocks are different?
