1. (10%) Let X be a random variable with probability density function given by Find the moment generating function for X.

(3) For i =, be the standardized version of the data, where are the sample mean and sample standard deviation for y over these i observations, and are the sample mean and sample standard deviation for tj. j = 1.2. . k. Now we regress y* on 1 and xj, j = 1,2, , k, to yield the estimated model as where, j = O, 1. . ., k, are the associated OLS estimates. a. (10%) Find the OLS estimates= 0, 1, b.
