Question

Given below is a bivariate distribution for the random variables x and y. f(x, y) x y 0.2 50 80 0.3 30 50 0.5 40 60 (a) Compute the expected value and the variance for x and y. E(x)

Answer 1

Complete data:

f(x,y) x Y

0.2 50 80

0.3 30 50

0.5 40 60

Answer:

Expected values for x and Y

E(x) = 39, E(Y) = 61

Variance for x and Y

E(x^2) = 1570

E(Y^2) =3830
