(10 points) Suppose we assume a new linear model Where we assume ,80 = 0 so that 3'2 = 51$; + 8::- As usual, we also assume the si's are independent and identically distributed random variables with E (51) = 0. Find the least squares estimator of Bl. (This model, which describes a straight line passing through the origin, is called the no intercept model.)
