Question 8 of 10 This test: 10 point(s) possible This question: 1 point(s) possible Submit test A pediatrician wants to determine the relation that exists between a child's height, x, and head circumference, y. She randomly selects 11 children from her practice, measures their heights and head circumferences, and obtains the accompanying data. Complete parts (a) through (9) below.

One has a head circumference of 17.6 inches; the other has a head circumference of 17 8 inches. How can this be? O A. There is no logical explanation for this-the two observations in question should have had the same head circumference. O B. The only explanation is that the difference is due to the fact that one observation was of a boy, and one observation was of a girl. O C. The only explanation is that the difference was caused by measurement error. O D. For children with a height of 26.75 inches, head circumferences vary. (g) Would it be reasonable to use the least-squares regression line to predict the head circumference of a child who was 32 inches tall? Why? O A. No- this height is not possible. O B. No-this height is outside the scope of the model 4 O C. Yes-the calculated model can be used for any child's height Next
