1.2 Consider the following five points: Name X-Value Y-Value L. (a) Plot the five points and the centroid. Be sure that Y is the vertical axis and X is the horizontal axis. (b) Draw a line that appears to fit the five points. (c) Find the bo and b, for the line you drew in part (b). (d) Find the residuals. Specifically, calculate e,Yb bX) for H J, K, L, and M. (e) Calculate the sum of the squared residuals (2 e) for the line drawn in part (b). (f) Now calculate the ordinary least squares bo and b, for the five points. Label them bo and b (8) Find the new residuals. Specifically, find e Y bbx) for i H J, K, L, and M. (n) Calculate the new sum of squared residuals (2 e2). o) Which line leads to the smaller sum of squared residuals? Does any line exist that leads to a smaller sum of squared residuals?
