A ) Figure 1
B ) Figure 2

Steps to derive

1 From the stem and leaf plot, the data can be divided into four ranges 10 - 19, 20 - 29, 30 - 39 and 40 - 49.

2 The count of numbers in the range 10 - 19 is 3.
 [The number of leaves with stem 1.]

3 The count of numbers in the range 20 - 29 is 5.
 [The number of leaves with stem 2.]

4 The count of numbers in the range 30 - 39 is 4.
 [The number of leaves with stem 3.]

5 The count of numbers in the range 40 - 49 is 5.
 [The number of leaves with stem 4.]

6 List the unique ranges and write the count of numbers in each range. The frequency table will be as shown.


7 So, the frequency table in Figure 1 is appropriate.
