Assignment Two Page 75, Problem 1.82 a) The deciles of the standard normal distribution are as follows: -1.28 is the point that marks off the lowest 10% and 1.28 is the point that marks off the highest 10%. We found these points by locating 10% and 90% in the Normal Tables and then we found the z values that corresponded to these numbers. The deciles of this distribution are as follows: 8.928 is the point that marks off the lowest 10% and 9.312 is the point that marks off the highest 10%. Page 99, Problem 2.12 Stocks and Bonds -100 -50 0 50 100 150 200 -50 0 50 100 150 200 250 300 350 Stocks Bonds . The overall pattern shows that there is a negative relation between stocks and bonds because most of the numbers lie in region 2 and region 4. The strength of the relationship is very low, because the points do not follow a clear form. Page 104, Problem 2.20
