Compute the coefficients for a least squares regression equation and write the equation, given the following sample statistics. a. x̄ = 50, ȳ = 100, s x = 25, s y = 75, r xy = 0.6, n = 60 b. x̄ = 60,...

Compute the coefficients for a least squares regression equation and write the equation, given the following sample statistics.
a. x̄ = 50, ȳ = 100, s_x
= 25, s_y
= 75, r_xy
= 0.6, n = 60
b. x̄ = 60, ȳ = 210, s_x
= 35, s_y
= 65, r_xy
= 0.7, n = 60
c. x̄ = 20, ȳ = 100, s_x
= 60, s_y
= 78, r_xy
= 0.75, n = 60
d. x̄ = 10, ȳ = 50, s_x
= 100, s_y
= 75, r_xy
= 0.4, n = 60
e. x̄ = 90, ȳ = 200, s_x
= 80, s_y
= 70, r_xy
= 0.6, n = 60
