We are interested in determining whether or not the variances of the sales at two small grocery stores are equal. A sample of 16 days of sales at each store indicated the following: Store A __Store B________ n1 = 16 n2 = 16 Mean 1 = 300 Mean 2 = 310 S1 = $12 S2 = $10 Are the variances of the populations (from which these samples came) equal?
