Question 5 The enrolment in a school during six consecutive years was as follows: 1555, 1670, 1750, 2013, 2040, 2126. Find the mean enrolment in the school during this period.Now, Mean enrolment in the school = (𝑇𝑜𝑡𝑎𝑙 𝑒𝑛𝑟𝑜𝑙𝑚𝑒𝑛𝑡 𝑖𝑛 𝑡ℎ𝑒 𝑠𝑐ℎ𝑜𝑜𝑙)/(𝑁𝑢𝑚𝑏𝑒𝑟 𝑜𝑓 𝑦𝑒𝑎𝑟𝑠) = (𝟏𝟓𝟓𝟓 + 𝟏𝟔𝟕𝟎 + 𝟏𝟕𝟓𝟎 + 𝟐𝟎𝟏𝟑 + 𝟐𝟎𝟒𝟎 + 𝟐𝟏𝟐𝟔)/𝟔 = (11,154 )/6 Dividing both numerator & denominator by 2 = 5577/3 Dividing both numerator & denominator by 2 = 1,859 Thus, Mean enrolment in the school during this period is 1,859
