For the study of the effects of Martian height and water consumption on weight in Fig. 3-1, the amounts of water consumed fell into three distinct groups, 0, 10, and 20 cups/day. This fortuitous circumstance made it easy to draw Fig. 3-1 but rarely happens in practice. Substitute the following values for the column of water consumption data in Table 1-1, and repeat the regression analysis used to obtain Eq. (3.1): 2, 4, 6, 10, 8, 12, 18, 14, 16, 20, 22, 24.
