Question

a process for making ball bearings whose diameters

Answer 1

Answer:

A process manufactures ball bearings whose diameters are normally distributed with mean 2.505 cm and standard deviation 0.008 cm. Specifications call for the diameter to be in the interval 2.5 ± 0.01 cm. Let X represent the diameter of a randomly chosen ball bearing. Then X ∼ N(2.505, 0.0082).
