An agricultural company is trying to decide which type of fertilizer to use on its crops. The company concerned with the average yield on its crops as well as the variance of their yields. In a sample of 41 different fields with using fertilizer A, the average crop yield per acre is 184 tons with a standard deviation of 32 tons. In a separate sample of 41 different fields using fertilizer B, the average crop yield is 168 tons with a standard deviation of 26 tons. When testing the hypothesis (at the 1% level of significance) that the variance of one of these yields is significantly larger than the other, what is the test statistic? (please round your answer to 2 decimal places)
