We have been asked to find the number of students who scored 85 in math quiz from given stem and leaf plot. To answer this question let us know what is a stem and leaf plot is.
A stem and leaf plot represents numerical data by splitting the data into two parts known as leaf and stem.
Stem represents the first digit of the data, while leaf represents the last digit. We can use 15 as an example. In number 15 our stem will be 1 and 5 will be our leaf.
Now we will read our data. After reading our data we can see that two students of Mrs. James's class scored 85.
Now let us read data of Mrs. Cleveland's class. We can see that only one student scored 85.
Therefore option one is correct.
