Let X be the body mass index (BMI) and Y the systolic blood pressure of males, 50 years of age.
Given:
The average and variance of the BMI is X = 26 and Var(X) = 11.104.
The average and variance of the systolic blood pressure is Y = 132 and Var(Y) = 205.
The covariance between X and Y is Cov(X,Y) = 35.1.
