Stress is applied to a 20-in. Steel bar that is clamped in a fixed position at each end. Let Y be = 10 and Var(Y) = 100/7. the distance from the left end at which the bar snaps with E(Y) suppose U = Y/20 has a standard beta distribution: f(u; a, ß): = r(a+ß) α-1 น Γ(α)Γ(β) (1 −u)³-¹; 0 12). (d) Compute the probability that the bar snaps more or less than 2 in. from where you expect it to.
