The following data represent the calories and fat, in grams, of various 16-ounce iced coffee drinks.

Product Calories Fat
A 240 6
B 250 6.4
C 330 18.7
D 400 23.9
E 410 13.6
F 440 16
G 470 13.8
Compute the sample covariance.

Solution

Sum(Calories) = (240+250+330+400+410+440+470) = 2540

Mean(Sum) = 2540/7 = 362.85

Sum(Fat) = (6+6.4+18.7+23.9+13.6+16+13.8) = 98.4

Mean(Fat) = 98.4/7 = 14.057

Cov(X,Y) = 309.69

The following data represent the calories and fat, in grams, of various 16-ounce iced coffee drinks. Product Calories Fat A 240 6 B 250 6.4 C 330 18.7 D 400 23.
