3) Consider n pairs of numbers (x1, )1), (x2, V2), ..., and (X, )n). The mean and standard deviation of the x-values are x = 5 and s. = 4, respectfully. The mean and standard deviation of the y-values are y = 10 and sy = 10, respectively. Of the following, which could be the least squares regression line? (a) = -5.0 + 3.0x (b) y = 3.0x r ( 5 ) + 6 (c) y = 5.0 + 2.5x dDy = 8.5 + 0.3x (e) p = 10.0 + 0.4x
