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 61 type I ovens has a mean repair cost of $80.39, with a standard deviation of $13.81. A sample of 64 type II ovens has a mean repair cost of $73.75, with a standard deviation of $21.55. Conduct a hypothesis test of the technician's claim at the 0.1

0.1 level of significance. Let 1 be the true mean repair cost for type I ovens and 2 be the true mean repair cost for type II ovens.

Step1of4:State the null and alternative hypotheses for the test.
