Ball Weights An ISyE3770 student was asked to find the weigh

(Ball Weights; .An ISyE3770 student was asked to find the weights of two balls, A and B, using a scale with random measurement errors. When the student measured one ball at a time, the weights of A and B were 2 lbs and 3 lbs, respectively. However, if the student measured both balls simultaneously, then the total weight (A + B) was 4 lbs. Use the method of least squares in linear regression to find the best estimates of the weights of balls A and B.
