Determine q and r in the regression model y = qx + r (where x is mother's height and y is number of f's). (b) delete student e from your study and repeat part (a). does deleting e make much of a difference? (c) repeat the calculations in part (b) by first shifting the .,t-values to make the average x-value be o [see equations (21)].

m1=5,m2=0

compare the two slopes in the decimal form. if the slopes are equal, then the lines are parallel. if the slopes are not equal, then the lines are not parallel.
