Answer 2

Answer:

B. 63 students

Step-by-step explanation:

Total number of students=360

number of students Shawna asked=40

which is equal to 1/9 of the total population.

The number of clubs that the students joined are:

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

Hence, number of students who joined 3 clubs out of 40=7

We are given that this sample is representative of the student population of 360 students.

Hence, total number of students who joined 3 clubs= 7×9

                                                                                      =63

Hence, correct option is:

B. 63 students
