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. Use your calculator to draw a scatter diagram. Using the scatter diagram (no calculations), would you estimate the linear correlation coefficient to be positive, close to zero, or negative? x (inches) 20 24 36 41 46 y (pounds) 2 4 12 15 20
