The cooking times of a turkey in a 325°F oven are shown in Table 65 for various weights.

For a 325°F oven, let T be the cooking time (in hours) of a turkey that weighs W pounds.
a. Identify the explanatory and response variables.
b. Construct a scatterplot by hand.
c. Is the association positive or negative? What does that mean in this situation?
d. Graph the model T = 0.24W + 1.64 by hand on the scatterplot. Does the line come close to the data points?
e. Predict the cooking time for a 20-pound turkey in a 325°F oven.
