HW Problem 38. (5 pts) A machine at a production firm produces a component that is supposed to weigh 8.3 pounds. If the weight of the component varies significantly from that, the machine must be shut down and recalibrated. To see if this is necessary, the firm's quality control manager randomly samples 20 components as they come off the production line. This results in a sample mean weight of 8.37 pounds with a sample standard deviation of . 189 pounds. At the .01 level significance, is there enough to support the machine being shut down and recalibrated? List and clearly label all eight steps
