You are at a college of roughly 1,000 students and obtain data from the entire freshman class (250 students) on height and weight during orientation.
 
  You consider this to be a population that you want to describe, rather than a sample from which you want to infer general relationships in a larger population. Weight (Y) is measured in pounds and height (X) is measured in inches. You calculate the following sums:
 
   = 94,228.8, = 1,248.9, = 7,625.9
 
  (small letters refer to deviations from means as in =  ).
 
  (a) Given your general knowledge about human height and weight of a given age, what can you say about the shape of the two distributions?
  (b) What is the correlation coefficient between height and weight here?
  What will be an ideal response?
