A random sample of size nį = 38 yields a standard deviation of 8.6, and a random sample of size n2 = 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. %3D 1. The alternate hypothesis is Ha: Ο σισ O < s O s1 < 82 2. This is a left tailed test with: dfn = and dfa %3! 3a. The STS (to 2 decimals) is F %3D 3b. The P-value (to 3 decimals) is: 4a. At a = 0.05, the decision is: %3D O Accept Ho Do not reject Ho Reject Ho Accept Ha 4b. The conclusion is: There is insufficient evidence to support the claim that o is less than a O There is sufficient evidence to reject the claim that o, is less than a There is sufficient evidence to support the claim that o, is less than a2 There is insufficient evidence to reject the claim that o is less than oa
