A substance used in biological and medical research is shipped by airfreight to users in cartons of 1,000 ampules. The data below, involv- ing 10 shipments, were collected on the number of times the carton was transferred from one aircraft to another over the shipment route (X) and the number of ampules found to be broken upon arrival (Y). Assume the first-order regression model Yi = Bo + B1Xi+€, i=1,.. 10 is appropriate. i X; Y;₁ 1 2 3 5 6 7 8 9 10 1 0 3 0 2 0 16 9 17 12 22 13 8 15 19 11 4 (a) Obtain the estimated regression function. Plot the estimated regression function and the data. Does a linear regression function appear to give a good fit here? (b) Obtain a point estimate of the expected number of broken ampules when X = 1 transfer is made. (c) Obtain the residual for the first case. What is its relation to €₁? (d) Compute and MSE.
