Suppose the data shown here are the results of a survey to investigate gasoline prices. Ten service stations were selected randomly in each of two cities and the figures represent the prices of a gallon of unleaded regular gasoline on a given day. Use the F test to determine whether there is a significant difference in the variances of the prices of unleaded regular gasoline between these two cities. Let α = .01. Assume gasoline prices are normallydistributed.
