b. For the given data, compute each of the following: 7 = 7: Ex = 5y: x2= Xy' = Exy= c. The equation of the least-squares line: 57=a+bx = d. Graph the least squares line on your scatter diagram (show the three points you are plotting here). 1. Taltson Lake is in the Canadian Northwest Territories. This lake has many northern pike. The following data was obtained by two fishermen visiting the lake. Let x = length of a northern pike in inches and let y = weight in pounds. x (inches) 20 24 36 41 46 y (pounds) 2 4 12 15 20 a.
