You are a line manager in Super Car Partâ€™s Eversville manufacturing facility. The company produces automotive parts, and you have responsibility for the line producing steel shafts for the gearbox manufactured in the Eversville Plant. The acceptable dimension of the shaft is 2.5Â±0.05 inches in diameter with the most desirable product having a diameter of exactly 2.5 inches. The current equipment is approaching the end of its useful life and needs to be replaced. Two vendors are trying to sell your company, Super Car Parts Incorporated, their machines for the shaft-machining task. You have been asked to assess the machines from each vendor, and to make a recommendation for a machine vendor supported by a justification for your decision.
You asked both vendors to supply data on the machining accuracy of their machines for the given task. Both vendors machined 100 shafts, collected data, plotted histograms, fitted the histograms with normal distributions and supplied you with their findings.
Let X= diameter in inches of the gearbox shaft
Aballo Machines Inc.: X has a normal distribution with a mean of 2.49 and a standard deviation of 0.030
Lu Equipment Corp.: X has a normal distribution with a mean of 2.53 and a standard deviation of 0.015
