The electricity generation problem: Most of S.A's power stations are coal- fired. Assume a random sample of 10 power stations were selected and their coal usage and electricity generated 2017 was obtained. Coal used in 2017 15 6 10 18 9 7 14 11 5 8 (in million tonnes) Electricity generated (million kilowatt hours) 35 18 24 32 24 20 32 29 14 22 Find the straight-line regression function to estimate electricity generated (y) from coal used (x) by the method of least squares. OAS=5.7634 2.815K O B.§=9.367+1.51&x OCf=9.367+1.518y OD.Î=5.763+2.815y
