Question 4 (1 point) We are checking the costs of microwave oven repairs. Test whether Model A repair costs are lower than Model B's. We research the repair costs of 34 Model A ovens and 20 Model B ovens. The results on the repair costs are shown in the table below. Modem \" Modem At a 0.10 level of signicance, are the costs of repair for the model A less than model B? Assume the samples are randomly selected from the populations that are normally distributed. Assume the population variances are unequal. Denote by #1 and [12 the mean repair costs for all Model A and Model B ovens, respectively. Test the appropriate hypotheses. What is the statistical decision? Interpret your decision. Q Do not reject Ho. There is no evidence that the costs of repair for the model A less than model B. O Reject Ho. There is evidence that the costs of repair for the model A less than model B. Q Do not reject Ho. There is evidence that the costs of repair for the model A less than model B. O Reject H1. There is no evidence that the costs of repair for the model A less than model B. O Reject Ho. There is no evidence that the costs of repair for the model A less than model B
