#Question 3:0LS regression and data generation [25 points] #In this question, you are going to generate sets of data and run regression. #Suppose the true relationship between Yi and Xi is captured by: #Yi =3+0.7Xi +epsilon(i) #E[epsilon(i)|Xi]=0; epsilon(i) is drawn from a normal distribution with mean=0 and sd=1 #Xi is a normal distribution with mean=2 and sd=sqrt(3) #(a) [5 points] Generate an N=100 sample called X from a population normal distribution with mean=2 and sd=sqrt(3). #Your codes here: X
