A random sample of size nį = 38 yields a standard deviation of 8.6, and a random sample of size nz = 36
yields a standard deviation of 10.5.
At a = 0.05, 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:
Ο σι< σ
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 = 0.05, the decision is:
O Accept Ho
O Do not reject Ho
O Reject Ho
O Accept Ha
4b. The conclusion is:
O There is insufficient evidence to support the claim that o, is less than o,
O There is sufficient evidence to reject the claim that o, is less than a2
O There is sufficient evidence to support the claim that o is less than a2
O There is insufficient evidence to reject the claim that o, is less than oa
