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 Il ovens. A sample of 60 type l ovens has a mean repair cost of $74.06, with a standard deviation of $16.10. A sample of 68 type Il ovens has a mean repair
cost of $67.73, with a standard deviation of $14.70. 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 uz be the true mean repair cost for type Il ovens.
