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).
