Short Answer – 2

Many manufacturing problems involve the accurate
matching of machine parts such as shafts that fit
into a valve hole. A particular design requires a shaft
with a diameter of 22.000 mm, but shafts with
diameters between 21.900 mm and 22.010 mm are
acceptable. Suppose that the manufacturing process
yields shafts with diameters normally distributed
with a mean of 22.002 mm and a standard deviation
of .005 mm. If a random sample of 36 shafts is
chosen from the above process, what is the
probability of the sample mean being above 20.003
mm?
