(b) Montenegro has a really low trade balance of -45.3. Kuwait, 42.2, and Libya, 40.7, have really high trade balances. (c) . . . . . The distribution and numerical summaries are almost identical before and after the outliers are removed. (d) Overall, the distribution is very symmetrical so that if some countries export a lot, there are other countries that import just as much. The mean and median trade balance is very close to 0. The outliers had almost no effect on the distribution or numerical summaries. Essentially, the outliers form longer tails on the curve.
