Answer 2

The stem-leaf plot is attached below

Answer:

According to the plot, 75% of students read less than 35 pages ⇒ 3rd answer

Explanation:

At first lets count the number of the students from the picture

There are 4 students in the 1st row

There are 6 students in the 2nd row

There are 6 students in the 3rd row

There are 3 students in the 4th row

There are 3 students in the 5th row

There are 1 student in the 6th row

The total number of students = 4 + 6 + 6 + 3 + 3 + 1 = 23

Let us find 75% of them equals how many students

75% × 23 =
`(75)/(100)` × 23 = 17.25

That means 75% of the students is about 17 students

Let us find the 17th student read how many pages

From the chart the 17th students read 33 pages

The 18th student read 35 pages

So 75% of the students read less than 35 pager

According to the plot, 75% of students read less than 35 pages
