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 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 uj be the true mean repair cost for type I ovens and uz be the true mean repair cost for type II ovens. Step 3 of 5: Find the p-value associated with the test statistic. Round your answer to four decimal places.

Transcribed Image Text: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 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 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 µj be the true mean repair cost for type I ovens and µz be the true mean repair cost for type II ovens.
Step 3 of 5: Find the p-value associated with the test statistic. Round your answer to four decimal places.
