Atechnician 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 60 type i ovens has a mean repair cost of $⁢85.79, with a standard deviation of $⁢15.13. a sample of 56 type ii ovens has a mean repair cost of $78.67, with a standard deviation of $⁢17.84. conduct a hypothesis test of the technician's claim at the 0.1 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 1 of 4: state the null and alternative hypotheses for the test. step 2 of 4: compute the value of the test statistic. round your answer to two decimal places. step 3 of 4: determine the decision rule for rejecting the null hypothesis h0. round the numerical portion of your answer to three decimal places. step 4 of 4: make the decision for the hypothesis test. reject or fail to reject null hypothesis
