Problem 2


11.9 Using the Model to Create a Prediction Interval

The least squares line for the relationship between the height and weight for super models from problem 40 was y-hat = 3.88X -152. Find the 99% prediction interval for a model’s weight given that the model was 73 inches tall (n = 9, X-bar = 70.2222, SSxx =19.05556, S = 4.8789).
