The General Social Survey asked a sample of adults how many siblings (brothers and sisters) they had (X) and also how many children they had (Y). We show results for those who had no more than 4 children and no more than 4 siblings. Assume that the joint probability mass function is given in the following contingency table. 2 3 х 0.03 0.01 0.02 0.01 0.01 0.09 0.05 0.08 0.03 0.01 0.04 2 0.09 0.05 0.07 0.02 3 0.06 0.04 0.07 0.04 0.02 0.03 0.02 4 0.04 0.03 0.04 Find µx+Y• a.
