A process manufactures ball bearings with diameters that are normally distributed with mean 25.15 mm and standard deviation 0.08 mm. a) A particular ball bearing has a diameter of 25.2 mm. What percentile is its diameter on? (Round up the final answer to the nearest whole number.) b) To meet a certain specification, a ball bearing must have a diameter between 25.0 and 25.3 millimeters. What proportion of the ball bearings meet the specification?

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 bearing can operate are 0.72 inch (lower) and 0.74 inch (upper). Past experience has indicated that the actual diameter of the ball bearings is approximately normally distributed, with a mean of 0.732 inch and a standard deviation of 0.006 inch. Suppose a random sample of 21 ball bearings are selected. Complete parts (a)...
