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. Height Head Circumference.

Does a linear relation exist between height and head circumference? OA. Yes, there appears to be a positive linear association because ris positive and is greater than the critical value. OB. Yes, there appears to be a positive linear association because r is positive and is less than the critical value. OC. Yes, there appears to be a negative linear association because r is negative and is less than the negative of the critical value OD. No, there is no linear association since r is positive and is less than the critical value

(d) Determine if a linear relation exists between height and head circumference. (Note that the
linear correlation coefficient between the height and head circumference of a child is r=0.888)
Find the critical value
The critical value is
(Round to three decimal places as needed.)
Does a linear relation exist between height and head circumference?
QA. Yes, there appears to be a positive linear association because ris positive and is
greater than the critical value.
OB. Yes, there appears to be a positive linear association because r is positive and is less
than the critical value.
OC. Yes, there appears to be a negative linear association because ris negative and is less
than the negative of the critical value.
OD. No, there is no linear association since r is positive and is less than the critical value
