W 13. Height versus Head Circumference A pediatrician wants to determine the relation that may exist between a child's height and head circumference. She randomly selects 11 children from her practice, measures their heights and head circumferences, and obtains the following data: Height Head Height Head (inches), Circumference (inches), Circumference (inches), y (inches), y 27.75 17.5 26.5 17.3 24.5 17.1 17.5 17.1 26.75 17.3 26 17.3 26.75 17.5 25 16.9 17.5 27.75 17.6 Source: Denise Slucki, student at Joliet Junior...
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.
