A pediatrician wants to determine the relation that may exist between a child's height and Height (in.) Head Circumference (in.) head circumference. She randomly selects 8 children from her practice, measures their 27.25 17.3 height and head circumference, and obtains the data shown in the table. Complete parts 25.25 16.9 (a) through (e) below. 26.75 17.2 Click here to see the Table of Critical Values for Correlation Coefficient. 25.25 16.9 27.75 17.4 26.25 17.3 26.25 17.2 27 17.3 The explanatory variable is height and the response variable is head circumference. O The explanatory variable is head circumference and the response variable is height. (b) Draw a scatter diagram. Choose the correct graph below. O A. OB. *C. XD. 17.6 28- 17.6 28- Circ. (in.) Circ.
