Calculate the mean for the following distribution.
| $x$ | 5 | 6 | 7 | 8 | 9 |
| $f$ | 4 | 8 | 14 | 11 | 3 |
To do:
We have to find the mean for the given distribution.
Solution:
| $x$ | $f$ | $f \times\ x$ |
| 5 | 4 | 20 |
| 6 | 8 | 48 |
| 7 | 14 | 98 |
| 8 | 11 | 88 |
| 9 | 3 | 27 |
| Total | 40 | 281 |
Mean$=\frac{\sum fx}{\sum f}$
Therefore,
Mean $=\frac{281}{40}$
$=7.025$
The mean of the given distribution is $7.025$.
