Please stap by step answer

A technician compares repair costs for two types of microwave ovens (type land type I), He believes that the repair cost for type I ovens is greater than the repair cost for type ll ovens. A sample of 32 type I ovens has a mean repair cost of S89.74, with a standard deviation of S10.39. A sample of 49 type Il ovens has a mean repair cost of S83.08, with a standard deviation of $11.67, Conduct a hypothesis test of the technician's claim at the 0.1 level of significance. Let ji be the true mean repair cost for type I ovens and a be the true mean repair cost for type l ovens Step 2 of 4: Compute the value of the test statistic. Round your answer to two decimal places.
