Question
A random sample of size ni = 40 yields a standard deviation of 9.1, and a random sample of size na = 30
yields a standard deviation of 10.4.
At a = 0.01, 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:
O 01 < 02
O s1 < 82
O s < s?
2. This is a left tailed test with:
d fn =
and dfa =
3a. The STS (to 2 decimals) is F =
%D
3b. The P-value (to 3 decimals) is:
4a. At a = 0.01, the decision is:
O Reject Ho
O Accept Ha
