Let Y have a truncated distribution with pdf g(y) = (y)/[(b)(a)], for a < y < b,
Question:
Let Y have a truncated distribution with pdf g(y) = φ(y)/[Φ(b)−Φ(a)], for a < y < b, zero elsewhere, where φ(x) and Φ(x) are, respectively, the pdf and distribution function of a standard normal distribution. Show then that E(Y) is equal to [φ(a) − φ(b)]/[Φ(b) − Φ(a)].
