Sometimes, data must be modified before a stem-and-leaf plot may be constructed. For example, the data in the accompanying table represent the 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 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. Complete parts (a) through (c) below.

(a) Round the data to the nearest tenth. 10.12 9.12 11.82 10.34 11.12 9.89 9.16 ~ 8.18 ~ 8.08 ~ 10.03 10 11.76 10.55 11.61 ~ 10.66 ~ 9.49 11.47 Print Five-year rate of return of mutual funds 10.12 9.12 8.08 11.61 9.59 11.82 10.34 10.03 10.66 11.22 11.12 9.89 11.76 9.49 11.72 8.18 9.16 10.55 11.47 8.45 9.59 11.22 11.72 8.45 Done C X

we have to round all the data values in nearest tenth means in 1 decimal places 

as we know rule of rounding that if the last digit is more than or equal to 5 then add 1 to the second last digit

and if the last digit is less than 5 then keep second last digit as it is
