A technician compares repair costs for two types of microwave ovens (type I and type II)....

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 34 type I ovens has a mean repair cost of $71.37, with a standard deviation of $18.58. A sample of 31 type II ovens has a mean repair cost of $66.93, with a standard deviation of $24.60. Conduct a hypothesis test of the technician's claim at the 0.01 level of significance. Let μ1 be the true mean repair cost for type I ovens and μ2

be the true mean repair cost for type II ovens.

Step 2 of 4 :

Compute the value of the test statistic. Round your answer to two decimal places.

In a random sample of five microwave​ ovens, the mean repair cost was ​$65.00 and the standard deviation was ​$13.50. Assume the population is normally distributed and use a​ t-distribution to construct a 90​% confidence interval for the population mean mu. What is the margin of error of mu​? Interpret the results. The 90​% confidence interval for the population mean mu is ​( nothing​, nothing​). ​(Round to two decimal places as​ needed.)
