o=100 The rate of service of a component is a normally distributed

o=100 The rate of service of a component is a normally distributed with mean of 145 hours and hours. If it has been manufactured correctly a defect in the manufacturer result is shorter life time for the component from a large lot which side all good and all defective one. 10 items are chosen, tested and formed to have an average life time of 132 hours. Should the lot be accepted if we require the probability of rejecting a good lot to be less than 0.02? If the lot has a mean of 130 hours, what would be the probability of accepting it?
