Construct a stem-and-leaf plot of the test scores:67, 72, 86, 75, 89, 89, 87, 90, 99, 100.67, 72, 86, 75, 89, 89, 87, 90, 99, 100. How does the stem-and-leaf plot show the distribution of these data?

Stem-and-leaf plot of the test scores is shown below.

Step-by-step explanation:

The given data set is

67, 72, 86, 75, 89, 89, 87, 90, 99, 100

Stem-and-leaf: Leaf is the last term and stem is other term. If a number is 32, then 3 is stem and 2 is leaf.

Stem-and-leaf plot of the test scores is

Stem leaf

6 7

7 2,5

8 6,7,9,9

9 0,9

10 0

The length of the rows are similar to the heights of bars in a histogram; longer rows of the data correspond to higher frequency.
