Answer questions please

3. (8 points) Ball bearings are manufactured with a mean diameter of 5 millimeters (mm). Because of variability in the manufacturing process, the diameters of the ball bearings are approximately normally distributed, with a standard deviation of 0.02 mm. (a) What proportion of ball bearings has a diameter more than 5.03 mm? Show calculation. 5.03- 5,00 2 = P(x > 5.03) = 1- 0.9332= 0.02 = 1.5
