Compute the values of the least squares estimates of ????0 and ????1 and report the equation of the least squares regression line when

(a) ???? = 0.85, ????̄ = 25.2, ????̄ = 56.3, ???????? = 6.8, and ???????? = 12.7.

(b) ???? = −0.75, ????̄ = 117.5, ????̄ = 23.8, ???????? = 13.1, and ???????? = 8.8.

(c) ???? = 0.90, ????̄ = 4.3, ????̄ = 28.7, ???????? = 1.3, and ???????? = 5.6.
