Answer 1

By examining the stem-and-leaf plot, we can see that only one leaf with the value of 2 is next to the stem of 2, indicating that one student scored 22 on the quiz.

Step-by-step explanation:

To determine how many students scored 22 on the test, we need to look at the stem-and-leaf plot. The stem represents the tens place, while the leaf represents the ones place of a score. On this plot, the number 2 on the stem corresponds to the tens place of the scores in the 20s. Each leaf next to the stem represents a single student's score in the ones place.

According to the provided stemplot:

• 0 | 2 3 3 4 5 5 5 5 6 7 8 9
• 1 | 0 0 0 0 1 1 1 2 2 2 3 3 4 4 4 5 5 6 6 7 7 8
• 2 | 0 0 0 0 1 2 3 8 9 9
• 3 | 0 2 2 2 6 8
• 4 | key : 2 | 8 means 28

Looking at the stem with 2, we find one leaf with 2, which means one student scored 22.
