The enrolment in a school during six consecutive years was as follows: 1555, 1670, 1750, 2013, 2540, 2820. Find the mean enrolment of the school for this period.

Dear Student

Mean enrolment = Sum of all observations/ Number of observations = (555 + 1670 + 1750 + 2013 + 2540 + 2820)/ 6
= (12348/6)
= 2058
∴The mean enrolment of the school for this given period is 2058

Thanks
