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, S (2.2790 ) (0.3286) %3D %3D 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.)

Does how long young children remain at the lunch table help predict how much they eat? Twenty toddlers were observed over several months at a nursery school. "Time" is the average number of minutes a child spent at the table when lunch was served. "Calories" is the average number of calories the child consumed during lunch, calculated from careful observation of what the child ate each day. A regression was run and the results were: ý = 114 +1.2*x R² = 0.74 T = 0.858 Predict the number of calories a toddler consumes who remains at the table for 5 minutes (round your answer to two decimal places)
