Sometimes, data must be modified before a stem-and-leaf plot may be constructed. For example, the data in the accompanying table representthe five-year rate of return of 20 mutual funds and are reported to the hundredth decimal place. So, if we used the integer portion of the data as thand 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 macceptable since each leaf must be a single digit. To resolve this problem, we round the data to the nearest tenth. Complete parts (a) through (c)Click the icon to view the table of five-year rates of return.(a) Round the data to the nearest tenth.10.119.8911.188.279.04~10.368.939.288.2510.04≈8.8710.63(b) Draw a stem-and-leaf plot of the modified data.9.588.759.45~11.499.48≈11.24~8.77~8.57 ≈Legend: 810 represents 8.0(c) Describe the shape of the distribution. Choose the correct answer below.||||A. The distribution is skewed right because the right tail is longer than the left tail.OB. The distribution is skewed left because the left tail is longer than the right tail.

Here the given data values are :- We have to rounding these data values to the nearest tenth.
