The central limit theorem can be used to analyze round-off error. Suppose that the roundoff error is represented as a uniform random variable on [−1, 1]. If 100 numbers are added, approximate the probability that the round-off error exceeds (a) 1, (b) 2, and (c) 5. - In particular, how do you find the variance of this sum?
