The following data shows the results of a survey about gas prices. Ten service stations were selected randomly in each of two cities and the figures represent the prices of a liter of regular gas 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 gas between these two cities. Let a = 0.01. Assume gas prices are normally distributed. (You are not allowed to use F test function in Excel) (Round the intermediate values to 7 decimal places. Round your answer to 4 decimal places.) City 1 1.027 1.295 1.010 1.326 1.322 1.010 1.322 1.010 1.278 1.303 City 2
