Sometimes, data must be modified before a stem-and-leaf plot may be constructed. For example, the five-year rate of return data in Table 12 on page 79 is reported to the hundredth decimal place. So, if we used the integer portion of the data as the stem and the decimals as the leaves, then the stems would be 8, 9, 10, . . . , 19; but the leaves would be two digits (such as 94, 53, and so on). This is not acceptable since each leaf must be a single digit. To resolve this problem, we round the data to the nearest tenth.
(a) Round the data to the nearest tenth.
(b) Draw a stem-and-leaf plot of the modified data.
(c) Describe the shape of the distribution.
