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 s greater than the repair cost for type II ovens. A sample of 35 type I ovens has a mean repair cost of $80.39. The population standard deviation for the repair of type I ovens is known to be $24.63. A sample of 31 type Il ovens has a mean repair cost of $73.47. The population standard deviation for the repair of type Il ovens is known to be $10.42. Conduct a hypothesis test of the technician's claim at the 0.05 level of significance. Let u 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 5: State the null and alternative hypotheses for the test.

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 35 type I ovens has a mean repair cost of $80.39. The population standard
deviation for the repair of type I ovens is known to be $24.63. A sample of 31 type II ovens has a mean repair cost of $73.47. The
population standard deviation for the repair of type II ovens is known to be $10.42. Conduct a hypothesis test of the technician's claim at
the 0.05 level of significance. Let i be the true mean repair cost for type I ovens and µz be the true mean repair cost for type II ovens.
Step 1 of 5: State the null and alternative hypotheses for the test.
