A technician compares repair costs for two types of microwave ovens (type I and type Il). He believes that the repair cost for type l ovens is greater than the repair cost for type Il ovens. A sample of 62 type I ovens has a mean repair cost of $86.71, with a standard deviation of $11.53. A sample of 61 type Il ovens has a mean repair cost of $79.77, with a standard deviation of $13.41. Conduct a hypothesis test of the technician's claim at the 0.05 level of significance. Let jHi be the true mean repair cost for type I ovens and u; be the true mean repair cost for type ll ovens. Step 3 of 4: Determine the decision rule for rejecting the null hypothesis Hp. Round the numerical portion of your answer to three decimal places.

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 l ovens is greater than the repair cost
for type Il ovens. A sample of 62 type I ovens has a mean repair cost of $86.71, with a standard deviation of $11.53. A sample of 61 type Il ovens has a mean repair
cost of $79.77, with a standard deviation of $13.41. Conduct a hypothesis test of the technician's claim at the 0.05 level of significance. Let , be the true mean repair
cost for type l ovens and uz be the true mean repair cost for type l ovens.
Step 3 of 4: Determine the decision rule for rejecting the null hypothesis Ho. Round the numerical portion of your answer to three decimal places.
