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?
