Uniform distribution

X_1,X_2,...,X_n are independent and uniformly distributed on [0,1]
a. standardize X_1+X_2+...+x_n
b. Give mgf of THE STANDARDIZED (a) sum.

2. Suppose X is normal with mean u and variance sigma^2.
P{u<= X <= u + 1.5 sigma}

Solution Summary

This shows how to standardize the sum of variables and find the MGF.
