You want to buy a microwave oven and will choose Model A if its repair costs are lower than Model B's. You research the repair costs of 48 Model A ovens and 54 Model B ovens. The results of your research are shown in the figure to the right. At a= 0.01, would you buy Model A? Assume the samples are randomly selected and that the samples are independent. Complete parts (a)-(e). Model A Model B x, = $88 X2 = $85 s, = $12.50 S2 = $15
