Question

Michael surveyed a random sample of students in his school about the number of sports they play. There are 300 students in Michael's school. Use the

results of the survey to estimate the number of students in Michael's school who play exactly one sport.

Answer 1

75 students

Explanation:

From the table, we can calculate the total number of students surveyed by Michael:

Total student surveyed = 13 + 15 + 32 = 60 students

We can see that out of the 60 students, 15 students played exactly one sport. Hence:

Proportion of students playing exactly one sport = 15 / 60 = 0.25

Based on the result of the survey, if they are 300 students, number of students playing exactly one sport is:

Number of students playing exactly one sport = proportion * total students = 0.25 * 300 students = 75 students
