Answer #1

Ans:- Here, to find out the average age teacher collect random sample of size 15.

so, here every single student of the class ( population) is chosen randomly,and  all possible samples (from the classes) of student's age are equally likely to occur, so it represent 'Simple Random Sampling'.
