Extracted text: We are interested in comparing the average study hours for economic majors at USC and UCLA. We drew two independent random samples of 18 observations from each of the universities. USC had X = 19.5 hours s=6 hours, and UCLA had X = 18.5 hours and s=3.2. a.Conduct a one-sided test for the equality of variances of the two populations (Ho: or²= 0z?) using a=0.05. b.Using the results of part a, conduct a test to determine if the two universities' average study hours for Econ majors is the same. Use a=0.10.
