Mean = 2.31
Solution:
Given data:
Number (x) : 0 1 2 3 4
Frequency (f) : 5 15 22 40 6
To find the mean of the given data:
![$\text{Mean} =\frac{\Sigma fx}{\Sigma f}](https://tex.z-dn.net/?f=%24%5Ctext%7BMean%7D%20%3D%5Cfrac%7B%5CSigma%20fx%7D%7B%5CSigma%20f%7D)
![$\text{Mean} =\frac{(0\times 5)+ (1\times15)+(2\times22)+(3 \times40)+(4\times6)}{5+15+22+40+6}](https://tex.z-dn.net/?f=%24%5Ctext%7BMean%7D%20%3D%5Cfrac%7B%280%5Ctimes%205%29%2B%20%281%5Ctimes15%29%2B%282%5Ctimes22%29%2B%283%20%5Ctimes40%29%2B%284%5Ctimes6%29%7D%7B5%2B15%2B22%2B40%2B6%7D)
![$=\frac{203}{88}](https://tex.z-dn.net/?f=%24%3D%5Cfrac%7B203%7D%7B88%7D)
= 2.306
= 2.31
Mean = 2.31
Option C is the correct answer.
