3. Quality Control Lot Bayes: A certain machine is in adjustment 95% of the times. When the machine is in adjustment, it produces perfect parts 99% of the times. Call “acceptable” parts that are not perfect. When such machine is out of adjustment it produces perfect parts 80% of the times. In a sample, 4 of 5 parts are perfect. What is the probability that the machine is in adjustment? **MUST show correct formula set up before plugging in values. Use P for perfect and A for acceptable. Bayes formula set-up must have correct probability notation. 4.
