Height (inches) Head Circumference (inches) 27.75 17.3 25 16.9 26.5 17.2 25.25 17 27.5 17.5 26.25 17.3 25.75 17.1 27 17.3 A pediatrician wants to determine the relation that may exist between a child's height and head circumference. She randomly selects 8 children, measures their height and head circumference, and obtains the data shown in the table. a) If the pediatrician wants to use height to predict head circumference, determine which variable is the explanatory variable and which is the response variable. The explanatory variable is height and the response variable is head circumference. The explanatory variable is head circumference and the response variable is height. Part 2 (b) Draw a scatter diagram. Which of the following represents the data? A. 16.9 17.6 25 28 Height (in.) Circ. (in.) A scatter diagram has a horizontal axis labeled "Height (inches)" from 16.9 to 17.6 in increments of 0.1 and a vertical axis labeled "Circumference (inches)" from 25 to 28 in increments of 0.5. The following eight approximate points are plotted, listed here from left to right: (16.9, 25); (17, 25.3); (17.1, 25.7); (17.2, 26.5); (17.3, 26.3); (17.3, 27); (17.3, 27.8); (17.5, 27.5). The points generally rise from left to right. B. 25 28 16.9 17.6 Height (in.) Circ. (in.) A scatter diagram has a horizontal axis labeled "Height (inches)" from 25 to 28 in increments of 0.5 and a vertical axis labeled "Circumference (inches)" from 16.9 to 17.6 in increments of 0.1
