Extracted text: 03/8 marks: choose A or B A: In an experiment, the following correspondence was found between temperature T (in °C) and kinematic viscosity v (in Centistokes) of an oil with a certain additive: 20 40 60 80 100 120 220 200 180 170 150 135 Find the least square line v= aT + b. Use this line to estimate the viscosity of the oil at T = 140 and T = 160.
