Transcribed Image Text:17-20 ▪ Suppose the random variable X takes on the values 0, 1,
and 2 with probabilities 0.2, 0.3, and 0.5, respectively. For each of
the following random variables Y, find the joint distribution of X
and Y, compute the covariance and the correlation, and sketch a
graph showing the relationship, between X and Y that includes the
range of values X = 0, X = 1, and X = 2.
17. Y = 3X + 1
9-12- For the following joint distributions, find the probabili-
ties for the random variable X - Y (the difference), and check
that E(X – Y) =E(X) – E(Y) and that Var(X – Y)= Var(X)+
Var(Y) if Cov(X, Y)=0.
9. The random variables X and Y in Exercise 1.
10. The random variables X and Y in Exercise 2, with variances
found in Section 7.2, Exercise 10.
