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 20,24,36,41,46Y 2,4,12,15,20

e. Compute the sample correlation coefficient r. f. Compute the coefficient of determination 2 g. What percentage of the variation in the weight of a northern pike is explained by the length and the least-squares line? h. What percentage of the variation in the weight of a northern pike is unexplained by the length and the least-squares line? i. If a 32-inch northern pike is caught, what is its weight as predicted by the least- squares line
