The table below gives the height and weight of four randomly selected University undergraduate women. What is the least squares error E for these data points? 
A. E = (150A + B - 60)2 + (155A + B - 55)2 + (165A + B - 70)2 + (170A + B - 62)2 B. E = 150(A + B - 60)2 + 155(A + B - 55)2 + 165(A + B - 70)2 + 170(A + B - 62)2 C. E = (150A - 60B)2 + (155A - 55B)2 + (165A - 70B)2 + (170A - 62B)2 D. E = (150A + 60B)2 + (155A + 55B)2 + (165A + 70B)2 + (170A + 62B)2 E. none of these
