Suppose a linear regression model is fit with 30 data points and the following estimated regression equation is: yi = 10.5 + 1.25x; [ Select ] And x = 15, SSE = 34.5, $2 = 15.2 ~t(1.25, 0.2847, df = 28) ~t(10.5, 4.2751, df = 28) What is the distribution of Bo? ~t(10.5, 4 -AN(10.5, 4.2751) -AN(1.25, 0.2847) [ Select ] -AN(10.5, 4.2751) ~t(1.25, 0.2847, df = 28) What is the distribution of B, ? ~t(1.25, 0.2847, df = 28) -AN(1.25, 0.2847) ~t(10.5, 4.2751, df = 28) What do we assume the distribution of e (the population error) to be? [ Select ] ~N(0,Sigma) where Sigma is a parameter we need to estimate. -N(15,1.11) Not enough information to answer the question ~N(0,1.11)
