We are interested in determining whether or not the variances of the sales at two small grocery stores are equal. A sample of 21 days of sales at Store A and a sample of 16 days of sales at Store B indicated the following. Store A n1=21, s1 squared=800Store Bn2=16, s2 squared = 400Compute the p-value and use it to test the above hypotheses.
