Option C:
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:
[tex]$\text{Mean} =\frac{\Sigma fx}{\Sigma f}[/tex]
[tex]$\text{Mean} =\frac{(0\times 5)+ (1\times15)+(2\times22)+(3 \times40)+(4\times6)}{5+15+22+40+6}[/tex]
[tex]$=\frac{0+ 15+44+120+24}{88}[/tex]
[tex]$=\frac{203}{88}[/tex]
= 2.306
= 2.31
Mean = 2.31
Option C is the correct answer.
