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 or type II ovens. A sample of 53 type I ovens has a mean repair cost of $86.26, with a standard deviation of $11.30. A sample of 57 type II ovens has a mean repair ost of $83.04, with a standard deviation of $20.67. Conduct a hypothesis test of the technician's claim at the 0.05 level of significance. Let u, be the true mean repair ost for type I ovens and uz be the true mean repair cost for type |I ovens. tep 1 of 4 : State the null and alternative hypotheses for the test.
