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 58 type I ovens has a mean repair cost of $86.94, with a standard deviation of $13.05. A sample of 50 type II ovens has a mean repair cost of $83.20, with a standard deviation of $16.36. Conduct a hypothesis test of the technician's claim at the 0.05 level of significance. Let μ1 be the true mean repair cost for type I ovens and μ2 be the true mean repair cost for type II ovens. Step 1 of 4 : State the null and alternative hypotheses for the test.
