Question

interpret the slope and y - intercept, if appropriate. select the correct choice below and, if necessary, fill in the answer box to complete your choice.
(a) for a head circumference of 0 inches, the height is predicted to be (round to three decimal places as needed.) in.
(b) for every inch increase in height, the head circumference increases by 0.170 in., on average.
(c) for every inch increase in head circumference, the height increases by (round to three decimal places as needed.) in., on average.
(d) for a head circumference of 0 inches, the height is predicted to be (round to one decimal place as needed.) in.
(e) it is not appropriate to interpret the y - intercept.
interpret the y - intercept, if appropriate. select the correct choice below and, if necessary, fill in the answer box to complete your choice.
(a) for every inch increase in head circumference, the height increases by (round to one decimal place as needed.) in., on average.
(b) for a height of 0 inches, the head circumference is predicted to be (round to one decimal place as needed.) in.
(c) for every inch increase in height, the head circumference increases by (round to one decimal place as needed.) in., on average.
(d) for a head circumference of 0 inches, the height is predicted to be (round to one decimal place as needed.) in.
(e) it is not appropriate to interpret the y - intercept.

Explanation:

The slope represents the average change in height per inch increase in head circumference. Given the slope is 0.170, rounding to one decimal place gives 0.2. The y-intercept (head circumference = 0 inches) is not meaningful as head circumference cannot be 0.

Answer:

Slope: A. For every inch increase in head circumference, the height increases by 0.2 in., on average (Round to one decimal place as needed.)
y-intercept: E. It is not appropriate to interpret the y-intercept.
