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 are as follows: ŷ R² = 0.55; r = 0.743 = 178 +2.7x Predict the number of calories a toddler consumes who remains at the table for 13.5 minutes. Round your answer to three decimal places, if necessary,
