Open in App

Solution

Mean $= \frac{Sum of observations}{Total number of observations}$
Or
Mean $= \frac{\sum f_{i} x_{i}}{\sum f_{i}}$
$f_{1} + f_{2} + \dots + f_{8} = 16 + 12 + 10 + 8 + 6 + 4 + 3 + 1$
$x_{1} + x_{2} + \dots + x_{8} = 3000 + 4000 + 5000 + \dots$
$f_{1} x_{1} + f_{2} x_{2} + \dots = 3000 \times 16 + 4000 \times 12 + \dots$

Mean $= \frac{305000}{60} = 5083.33$
