Answer 2

Answer:

75% students read less than 35 pages.

Step-by-step explanation:

The stem and leaf plot is given below

0    |   5   0   5   8  

1     |   2   3   5   8   8   9

2    |   2   4   6   7   7   7

3    |   3   5   6

4    |   2   4   6

5    |   7

Count the students in each row.

Row 1 = 4 students

Row 2 = 6 students

Row 3 = 6 students

Row 4 = 3 students

Row 5 = 3 students

Row 6 = 1 student

Total students = 23 students

75% of 23 students = 0.75/100 · 23 = 12.25 students

75% of 23 students ≅ 17 students

From the stem and leaf plot, 17th student read 33 pages while 18th student reads 35 pages.

Which means

75% students read less than or equal to 33 pages.

OR

75% students read less than 35 pages
