Question

The stem plot gives the ages and years of the 25 donors at a blood drive. Which of the following is the closest estimate to the percentile of the donor who is 24 years old?

a) 25th percentile
b) 40th percentile
c) 60th percentile
d) 75th percentile

Answer 1

The closest estimate to the percentile of the donor who is 24 years old is 12%.

Step-by-step explanation:

The stem plot shows the ages of the 25 donors at a blood drive. To determine the closest estimate to the percentile of the donor who is 24 years old, we need to find the position of the 24-year-old donor in the ascending order of ages.

Counting the values in the stem plot, we can see that there are 3 values (23, 24, 26) that are less than or equal to 24 years old. Since there are 25 donors in total, the percentile of the donor who is 24 years old is (3/25) * 100 = 12%.

Therefore, the closest estimate to the percentile of the donor who is 24 years old would be the 10th percentile, which is not provided as an option in the question.
