To draw a stem and leaf plot for the amount data, make use of the ten's digits as the stems and one's digits of the amount as the leaves.
Use 0, 1 and 2 as stems to prepare the stem and leaf plot.
[All the amounts in the table are less than $30.]
The leaves are the one's digits of the corresponding amounts written in increasing order.
List all the unique stems and the corresponding leaves of each stem in the increasing order.
So, plot 1 is the stem and leaf plot for the data in the table.
The number of leaves for the stems 0, 1 and 2 are 2, 5 and 2.
So, the maximum number of leaves is for stem 1.
Correct Answer is : Plot 1; 1
