An industrial sewing machine uses ball bearings that are targeted to have a diameter of 0.71 inch. The lower and upper specification limits under which the ball bearings can operate are 0.69 inch and 0.73 inch, respectively. Past experience has indicated that the actual diam of the ball bearings is approximately normally distributed, with a mean of 0.713 inch and a standard deviation of 0.004 inch. Complete parts ( through (e) below. a. What is the probability that a ball bearing is between the target and the actual mean? 0.2734 (Round to four decimal places as needed.) b. What is the probability that a ball bearing is between the lower specification limit and the target? (Round to four decimal places as needed.)
