Name of the student | Jim | Tony | Paul | Brad | Laura | Wilma | Katie | Emily | Carol |

Amount ($) | 8 | 12 | 25 | 6 | 13 | 20 | 18 | 14 | 16 |

Step: 1

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.

Step: 2

Use 0, 1 and 2 as stems to prepare the stem and leaf plot.

[All the amounts in the table are less than $30.]

Step: 3

The leaves are the one's digits of the corresponding amounts written in increasing order.

Step: 4

List all the unique stems and the corresponding leaves of each stem in the increasing order.

Step: 5

So, plot 1 is the stem and leaf plot for the data in the table.

Step: 6

The number of leaves for the stems 0, 1 and 2 are 2, 5 and 2.

Step: 7

So, the maximum number of leaves is for stem 1.

Correct Answer is : Plot 1; 1

Step: 1
