12. A Fortune study found that the variance in the number of vehicles owned or leased by sub- scribers to Fortune magazine is .94. Assume a sample of 12 subscribers to another maga- zine 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 H₂: o² = .94 to determine whether the variance in the number of vehicles owned or leased by subscribers of the other magazine differs from o² = .94 for Fortune. At a .05 level of significance, what is your conclusion?

12. A Fortune study found that the variance in the number of vehicles owned or leased by sub-
scribers to Fortune magazine is .94. Assume a sample of 12 subscribers to another maga-
zine 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 Ho: 0² = .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?
