Suppose the probability density function of the length of computer cables is f(x) = 0.1 from 1200 to 1210 millimeters. a) Determine the mean and standard deviation of the cable length. Mean = 1205 millimeters Standard deviation = 2.886 millimeters (Round the answer to 2 decimal places.) b) If the length specifications are 1195 < x < 1206, what proportion of cables is within specifications?
