During her lunch hour, Shawna asked 40 students how many after-school clubs they joined. The given list shows the number of clubs that the students joined. 2, 2, 3, 0, 3, 2, 4, 2, 1, 4, 3, 2, 4, 1, 0, 2, 1, 3, 2, 0, 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?
There are 7 students in the sample of 40 who joined three clubs, so the sample proportion is 7/40. Applying that proportion to 360 students gives (7/40) × 360 = 63 students, so the estimate is 63 students.
