(c) What is the Least-Squares Regression Line (LSRL) for this data? (Round your answers to three decimal places) weight = xheight) (d) If the height was 0 inches, what would be the predicted weight? (Round your answer to the nearest integer.) lbs Does this weight make sense? O Yes O No (e) Suppose the height of the child was 10 inches tall, what would be the predicted weight? (Round your answer to the nearest integer.) Does this weight make sense? Yes O No A (f) If we are going to make a weight prediction from a given height, we should only use height values that are between the maximum and minimum heights. What is the range of heights that we should use to predict a weight? to inches B (g) What is the predicted weight for a child that is 69 inches tall? (Round your answer to the nearest integer.) lbs Does this weight make sense? O Yes O No

What is the range of heights that we should use to predict a weight? to inches (g) What is the predicted weight for a child that is 69 inches tall? (Round your answer to the nearest integer.) lbs Does this weight make sense? O Yes O No (h) Find the data point on the graph that corresponds to the child with a height of 69 inches. Is the predicted weight found in the previous question greater than, less than, or equal to the actual value of their weight? The predicted weight is ---Select--- the actual value of the child's weight.
