HW 13.1-13.4 Score: 4:30 4524 answered 0 Question 16 v Compute the STS [to two decimals} for a comparison of two population standard deviations or variances given that: a. The sample variances are 19 for Population 1 and 19.3 for Population 2. F: b. The sample standard deviations are 19 for Population 1 and 19.3 for Population 2.

The sample standard deviations are 16.6 for Population 'I and 14.5 for Population 2. F: b. The sample variances are 16.6 for Population 1 and 14.5 for Population 2. F: . Question 18 v A random sample of size in = 34 yields a variance of 7.7, and a random sample of size 112 = 39 yields a variance of 5.8. At or = 0.01, test the claim that the variance of Population 1 exceeds the variance of Population 2. 1. The alternate hypothesis is Ha: (If :> 0'3 '12:} 0'1 ;> 0'2 2 2 :32 51 A {'1' 51 /-; 32 2. This is a right tailed test with: dn = and dfd = 3a. The STS [to 2 decimals] is F = 3b. The P-value [to 3 decimals) is: 4a. At or = 0.01, the decision is: '5?
