At a = 0.10, test the claim that the standard deviation of Population 1 is less than the standard deviation
of Population 2.
1. The alternate hypothesis is Ha:
Os < s
Ο σι < σ2
O s1 < 82
2. This is a left tailed test with:
dfn =
and dfa =
3a. The STS (to 2 decimals) is F =
3b. The P-value (to 3 decimals) is:
4a. At a
