A machine produces metal axels used in an auto-mobile suspension system. A random sample of 15 axels is selected, and the diameter is measured. The resulting data (in millimeters) are as follows: 8.23 8.20 8.24 8.25 8.20 8.24 8.21 8.26 8.26 8.25 8.23 8.23 8.19 8.28 8.24 Compute a 95% tolerance interval on the diameter of the axels.
