Question
The table below shows the production (in thousand units)
of a factory over 5 years. Find the average annual production over these 5 years (in thousand units).Solution
Sum of productions = 50 + 65 + 60 + 80 + 75 = 125 + 60 + 80 + 75 = 185 + 80 + 75 = 265 + 75 = 340 thousand units Average = 340 / 5 = 68 thousand units.
