Question

machine that produces ball bearings has initially been set SO that the true average diameter of the bearing it produces is 500 in. bearing is acceptable if its diameter is within .004 in of this target value. Suppose, however that the setting has changed during the course of production, SO that the bearings have normally distributed diameters with mean value .499 in and standard deviation .002 in. What is the percentage that will not be acceptable:

Step 1

According to the problem, a bearing is acceptable if its diameter is within .004 in of the target value of 500 in. This means that any bearing with a diameter between 499.996 in and 500.004 in is acceptable. Show more…
