A Fortune study found that the variance in the number of vehicles owned or leased by subscribers to Fortune magazine is 0.34. Assume a sample of 12 subscribers to another magazine provided the following data on the number of vehicles owned or leased: 1,1,2,2,1,2,2,2,1,1,3,2.                     Test the hypothesis: H0: σ2 = 0.34 to determine whether the variance in the number of vehicles owned or leased by subscribers of the other magazine differs from σ2 = 0.34 for Fortune. At a 0.05 level of significance, what is your conclusion?
