Consider the following bivariate observations (X, Y ), where X is the amount of
sugar intake for the observed individuals in a day in grams on average and Y is their weight.
Table 1: Bivariate table for (X,Y)
X 10 15 12 18 30 35 42 26 29 25
Y 63.4 66.5 65.2 64.1 70.6 68.5 75.9 68.2 71.4 67.8
Calculate
(a) Cov(X,Y).
(b) ρX,Y =Corr(X,Y).
