Suppose that a random sample of 192 twenty-year-old men is selected from a population and that their yields Weight=(-95.4336) +3.7824 x Height, R=0.778, SER-9.7920 (2.0640) (0.2976) where Weight is measured in pounds and Height is measured in inches. A man has a late growth spurt and grows 1.4400 inches over the course of a year. Construct a confidence interval of 90% for the person's weight gain The 90% confidence interval for the person's weight gain is (.) (in pounds). (Round your responses to two decimal places.)
