B) Given A Random Variable X, E(X) = 0.63 & Var (X) = 0.2331. Find E(x2) .Can You Help Mez?
1 Answer - Sort by: Date | Rating
Var(x) = E(x2) - (E(x))2
Var(x) + (E(x))2 = E(x2)
.2331 + .632 = E(x2)
.2331 + .3969 = E(x2)
.63 = E(x2)
Var(x) + (E(x))2 = E(x2)
.2331 + .632 = E(x2)
.2331 + .3969 = E(x2)
.63 = E(x2)
