Data were obtained about men belonging to a gym. The men had an average height of 69 inches with an SD of 3 inches, and they had an average weight of 180 pounds, with an SD of 20 pounds. The correlation between height and weight was r = 0.43. A scatterplot was made of the data with height on the horizontal axis and weight on the vertical axis; it was football shaped.A scatterplot was made of the data with height on the horizontal axis and weight on the vertical axis; it was football shaped. a) Using the regression line, a man who is 6 feet tall is predicted to weigh pounds. The typical size of the errors for predictions made using the regression line is pounds
