A technician compares repair costs for two types of microwave ovens (type I and type II). He believes that the repair cost for type I ovens is greater than the repair cost for type Il ovens. A sample of 59 type I ovens has a mean repair cost of $70.89, with a standard deviation of $24.74. A sample of 69 type Il ovens has a mean repair cost of $67.71. with a standard deviation of $18.77. Conduct a hypothesis test of the technician's claim at the 0.1 level of significance. Let u, be the true mean repair cost for type I ovens and u, be the true mean repair cost for type Il ovens.
