A Fortune study found that the variance in the number of vehicles owned or leased by subscribers to Fortune magazine is .94. Assume a sample of 12 subscribers to another magazine provided the following data on the number of vehicles owned or leased: 2, 1, 2, 0, 3, 2, 2, 1, 2, 1, 0, and 1.
a. Compute the sample variance in the number of vehicles owned or leased by the 12 subscribers.
b. Test the hypothesis H0: σ2 = .94 to determine whether the variance in the number of vehicles owned or leased by subscribers of the other magazine differs from σ2 = .94 for Fortune. At a .05 level of significance, what is your conclusion?
