To solve the part c, could anyone tell me how to find the Cov(X,Y)??since we need to use Corr(X,Y)=COV(X,Y)/sd(X)sd(Y) to find the correlation.

4. Suppose you wanted to know if men are more likely to get traffic tickets than women. Your teamsurveys a large sample of drivers. Let X represent a persons gender (0 for female, 1 for male), andY represent the number of traffic tickets obtained in the last year. The joint probability function is: y 10 0.09 0.211 0.20 0.42 0.01 0.09 ‘7’ "'“'!“'1..ua._.|m~ “WI-“‘- (c) [4] Find the correlation coeflicient between gender and number of car tickets. What does thisvalue tell us about the relationship between the variables?
