(Ex)(y) and B = to find the best fitting straight line, N

(Ex)(y) and B = to find the best fitting straight line, N In this question, you will use the regression formulas A = y= Ax+ B, through the following data points. Nxy - 2 ()2 - (1, 3) (2,5) (3,6) (4, 11) What is the value of N? (Give an exact answer.) N = 4 Calculate the following quantities. (Give exact answers.) Ex = 10 2x2 = 30 Exy = 87 Ey = 25 Use the regression formulas to find the equation of the best fitting straight line. y = 37.5x 87.5 -
