A company makes parts for a machine. The lengths of the parts must be within
certain limits or they will be rejected. A large number of parts were measured and the
mean and standard deviation were calculated as 3.1 m and 0.005 m respectively.
Assuming this data is normally distributed and 99.7% of the parts were accepted, what
are the limits?
