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 49 Model A ovens and 52 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. Model A Model B = $80 = $75 s, = $13.50 S2 = $15 Ta) iuurnuiy LIe Ciaii anIu Siate dnu na: What is the claim? O A. Model A's repair costs are the same as Model B's. B.

Choose the correct answer below. A. Fail to reject Hg. The standardized test statistic is not in the rejection region. B. Reject Hg. The standardized test statistic is not in the rejection region. OC. Reject H,. The standardized test statistic is in the rejection region. D. Fail to reject Hg. The standardized test statistic is in the rejection region. Interpret the decision in the context of the original claim. At the % significance level, there is evidence to the claim that the repair costs for Model A are for Model B.
