Extra problems for additional credit. 1. Derive the formula for the mean and standard deviation of a discrete uniform random variable over the range of integers a,a + 1 ,...,b . 2. A bearing assembly contains 10 bearings. The bearing diameters are assumed to be independent and normally distributed with a mean of 1.5 mm and a standard deviation of 0.025 mm. What is the probability that the
