Using this information, do the following: (a) For each case, compute the preferred 2 level for each voter. Identify the median voter, and indicate the 2 level chosen under majority voting. (2 points) (b) For each case, computer the D2 curve, and find the socially optimal level of z. (2 points) (c) For each case, compare the 2 level under majority voting with the socially optimal 2. Explain the difference (if any) between the two 2 values. (2 points)
