12-4 The following hypotheses are given.
A random sample of five observations from the first population resulted in a standard deviation of 12. A random sample of seven observations from the second population showed a standard deviation of 7. At the .01 significance level, is there more variation in the first population?© BrainMass Inc. brainmass.com October 4, 2022, 12:21 pm ad1c9bdddf
