A technician compares repair costs for two types of microwave ovens (type I and type lI). He believes that the repair cost for type I ovens is greater than the repair cost for type ll ovens. A sample of 58 type I ovens has a mean repair cost of $84.57, with a standard deviation of $12.03. A sample of 72 type II ovens has a mean repair cost of $81.69, with a standard deviation of $11.91. Conduct a hypothesis test of the technician's claim at the 0.1 level of significance. Let u, be the true mean repair cost for type l ovens and py be the true mean repair cost for type Il ovens. Step 3 of 4: Determine the decision rule for rejecting the null hypothesis Ho. Round the numerical portion of your answer to two decimal places.

![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 Il ovens. A sample of 58 type I ovens has a mean repair cost of $84.57, with a standard deviation of $12.03. A sample of 72 type Il ovens has a mean repair
cost of $81.69, with a standard deviation of $11.91. Conduct a hypothesis test of the technician's claim at the 0,1 level of significance. Let u, be the true mean repair
cost for type I ovens and u2 be the true mean repair cost for type Il ovens.
Step 3 of 4: Determine the decision rule for rejecting the null hypothesis Ho. Round the numerical portion of your answer to two decimal places.
