Probabilistic and Statistical Techniques It was found that the mean length of 100 parts produced by a lathe was 20.05 mm with a standard deviation of 0.02 mm. Find the probability that a part selected at random would have a length (a) between 20.03 mm and 20.08 mm (b) between 20.06 mm and 20.07 mm (c) less than 20.01 mm (d) greater than 20.09 mm Example
