Question
Consider a simple linear regression model Y; = Bo + B1X; + E;, where e; are in-
dependent identically distributed (iid) N(0, o²). Suppose the parameter values
are Bo = 200, B1 = 5.0, and o = 4.
a) Explain the meaning of the parameters Bo
Assume that the scope of the model includes X = 0.
200, В1
5.0, and o = 4.
b) What is the distribution of Y? What is the mean and variance for this
distribution?
