The first factor is: Survivors (X1=0), Fatalities (X1=1). The second factor is: No Belt (X2=0), Adult Belt (X2=1), and Child Seat (X2=2). The proportions are as follow:
X1 = 0 X1 = 1------------------------------X2=0 | 0.38 | 0.17X2=1 | 0.14 | 0.02X2=2 | 0.24 | 0.05
a) Find E(X1), V(X1), E(X2), and V(X2)
b) Find cov(X1,X2)
c) Find the correlation coefficient between X1 and X2. How would you interpret the result?
