Suppose that a random sample of 212 twenty-year-old men is selected from a population and that their heights and weights are recorded. A regression of weight on height yields Weight = (-105.3746) +4.1764 x Height, R = 0.859, SER = 10 8120 (2.2790 ) (0.3286) where Weight is measured in pounds and Height is measured in inches. A man has a late growth spurt and grows 1.5900 inches over the course of a year. Construct a confidence interval of 80% for the person's weight gain. The 80% confidence interval for the person's weight gain is ( ) (in pounds) (Round your responses to two decimal places.)
