Question
A random sample of size nį = 30 yields a variance of 7, and a random sample of size n2 = 30 yields a
variance of 9.1.
At a = 0.05, test the claim that the variance of Population 1 is less than the variance of Population 2.
1. The alternate hypothesis is Ha:
O 81 < 82
Ο σι< σ
2. This is a left tailed test with:
d fn =
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 Do not reject Ho
O Reject Ho
O Accept Ho
O Accept Ha
4b. The conclusion is:
O There is insufficient evidence to reject the claim that o is less than o,
O There is sufficient evidence to reject the claim that o is less than o
O There is sufficient evidence to support the claim that o is less than o
O There is insufficient evidence to support the claim that o is less than o
