Q1. Use the method of least squares to find the line y = A+ Bx that best fits the four points (-3, 3), (-1, 4). (1, 8) and (3, 9). Using squared paper, plot the four points and your line. Your calculator probably has a built-in function to calculate A and B; if you don't know how to use it, take a moment to learn and then check you own answers to this problem. Compare the results you have obtained using three methods and comment on the differences: 1) Least squares method; 2) Manual fitting: Just part 1) and part 2)
