Question
Find the mean of your sleeping hours during one week.
✓
Answer
We know that there are seven days in a week. Let the sleeping hours during a week are as follows:
Now, sum of the sleeping hours of one week
=8+7+6+7+6+7+8=49 h"
and number of days in a week =7
$
\therefore \quad \text { Mean }=\frac{\text { Total sleeping hours }}{\text { Total number of days }}=\frac{49}{7}=7 h
$
Hence, the mean of your sleeping hours during one week is 7 h .
| Days | Hours |
| Monday | 8 h |
| Tuesday | 7 h |
| Wednesday | 6 h |
| Thursday | 7 h |
| Friday | 6 h |
| Saturday | 7 h |
| Sunday | 8 h |
=8+7+6+7+6+7+8=49 h"
and number of days in a week =7
$
\therefore \quad \text { Mean }=\frac{\text { Total sleeping hours }}{\text { Total number of days }}=\frac{49}{7}=7 h
$
Hence, the mean of your sleeping hours during one week is 7 h .
