You sample shafts that are being manufactured by the swing shift. You want to know what percentage of the parts, that they produce are out side of the tolerances. The spec says that the parts should be 1.50 inch plus or minus .005. Use the following data to determine the mean and standard deviation. Once the mean and standard deviation are known use the information to determine the z-score and find the percentage of parts out side the tolerances. 1.506 1.497 1.503 1.505 1.494
