Question

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 II ovens. A sample of 6161 type I ovens has a mean repair cost of $80.39$⁢80.39, with a standard deviation of $13.81$⁢13.81. A sample of 6464 type II ovens has a mean repair cost of $73.75$⁢73.75, with a standard deviation of $21.55$⁢21.55. Conduct a hypothesis test of the technician's claim at the 0.10.1 level of significance. Let μ1μ1 be the true mean repair cost for type I ovens and μ2μ2 be the true mean repair cost for type II ovens.
