A company wants to use data it has collected to predict customer satisfaction (as a percentage) based on the price of its product. The company uses polynomial regression to produce the mode are satisfied with their purchase price, p. The coefficient of determination for this model is ? = 0.95. LAAS(p) 1.2 08 0.6 04 0.2 -1 8 10 11 12 13 14 -0.2 Does the polynomial model appropriately fit the data? O No, it does not appropriately fit the data because the data appear to be concave down and decreasing. O Yes, it appropriately fits the data because the data appear to be concave down and decreasing. O Yes, it appropriately fits the data because the points are all close to the curve, and 2 is so close to 1. O No, it does not appropriately fit the data because there is a curve to the data, and 2 is close to 1.
