Armspan and Height Leonardo da Vinci(1452−1519) drew a sketch of a man, indicatingthat a person’s armspan (measuring across theback with arms outstretched to make a “T”) is roughlyequal to the person’s height. To test this claim, we measuredeight people with the following results:
a. Draw a
b. Calculate the
c. If you were to calculate the regression line for predictingheight based on a person’s armspan, howwould you estimate the slope of this line?
d. Find the regression line relating armspan to a person’sheight.
e. If a person has an armspan of 62 inches, what wouldyou predict the person’s height to be?
