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 58 type I ovens has a mean repair cost of $88.52, with a
standard deviation of 23.72. A sample of 49 type II ovens has a
mean repair cost of $86.20$86.20, with a standard deviation of
$14.32. Conduct a hypothesis test...
