After Finishing College, You Start Working as a Quality Control

question 6

Essay

After finishing college, you start working as a quality control agent at a local manufacturing plant. The machine that you are in charge of produces steel bolts. Your job is to fine tune the machine so that it produces a specific size bolt, but a small margin of error is allowable. Suppose that you believe that the machine has been calibrated so that the actual size of a bolt produced has an approximate normal
distribution with a mean of 25 cm and a standard deviation of 0.001 cm. After producing 1000 bolts,
you randomly choose one and find that it measures 24.9995 cm. Based off of this measurement, do you think that the machine has been properly calibrated? Explain.
