1, 1, 2, 1, 0, 3, 0, 1, 4, 1, 1, 0, 2, 3, 2, 0, 3, 2, 0, 1

If this sample is representative of the student population of 360 students, about how many students in the school joined three clubs?

Answer 1

Number of 3s in the data = 7
360 / 40 = 9
9*7 = 63
63

Answer 2

Answer: There are 63 students who joined three clubs in 360 students .

Explanation:

Since we have given that

Number of students joined 3 clubs among 40 students = 7

So, if the number of students = 360

Then, the number of students in the school joined 3 clubs are

`(7)/(40)* 360\\\\=7* 9\\\\=63`

Hence, there are 63 students who joined three clubs in 360 students .
