Solution
The stem-and-leaf plot provided shows the scores of students on a science test. The stem represents the tens place of the score, and the leaf represents the ones place.
To find the number of students who scored 90% or better, we need to look at the stem values of 9 and 10 (representing 90-99% and 100% respectively).
According to the plot:
- For the stem value of 9 (90-99%), there are two leaves (1 and 6), which means two students scored in this range.
- For the stem value of 10 (100%), there is no leaf value mentioned, which means no student scored 100%.
So, adding these up, there are 2 students who scored 90% or better on the test.
