Recently, research efforts have focused on the problem of predicting a manufacturer’s market share by using information on the quality of its product. Suppose that the following data are available on market share, in percentage (Y), and product quality, on a scale of 0 to 100, determined by an objective evaluation procedure (X):

X: 27 39 73 66 33 43 47 55 60 68 70 75 82

Y: 2 3 10 9 4 6 5 8 7 9 10 13 12
