Scenario: A pediatrician wants to determine the relation that may exist between a child's height and head circumference . She randomly selects eleven 3-year old children from her practice, measures their heights and head circumference , and obtains the data shown below: Height (inches) 27.75 24.5 25.5 26 25 25.75 26.5 27 26.75 26.75 27.5 Head Circumference (inches ) 17.5 17.1 17.2 17.3 16.9 17.6 17.3 17.5 17.3 17.6 17.5 which a. If the pediatrician wants to use height to predict head circumference dete variable is the explanatory variable and which is response variable. b. Draw a scatter diagram of the data. Draw the best fit line on the scatter diagram . d. Does this scatter diagram show a positive negative, or no relationship between a child's height and the head circumference ?
