*round to 4 decimal places as needed*
An industrial sewing machine uses ball bearings that are targeted to have a diameter of \( 0.73 \) inch. The lower and upper specification limits under which the ball bearings can operate are \( 0.72 \) inch and \( 0.74 \) inch, respectively. Past experience has indicated that the actual diameter of the ball bearings is approximately normally distributed, with a mean of \( 0.733 \) inch and a standard deviation of \( 0.004 \) inch. Complete parts (a) through (e) below. a. between the target and the actual mean? b. between the lower specification limit and the target? c. above the upper specification limit? d. below the lower specification limit?
