8.10. ink Suppose y is known to be linear in I, so that y = A + Bx, and we have three measurements of (x, y): (1, 2 a 0.5), (2, 3 a 0.5), and (3, 2 i 1). (The uncertainties in .x are negligible.) Use the method of weighted least squares, Equations (8.3?) to (8.39), to calculate the best estimates for A and B. Compare your results with what you would get if you ignored the variation in the uncertainties, that is, used the unweighted t of Equations (8.10) to (8.12). Plot the data and both lines, and tr).r to understand the differences
