Answer: 95% of all people work between 7 hours and 9 hours per day and It is true.
Step-by-step explanation:
Since we have given that
Mean = 8 hours
Standard deviation = 0.5 hours
According to Empirical Rule,
at 95% confidence, it lies within 2 standard deviations from the mean
so, lower value is given by

upper value is given by

Hence, 95% of all people work between 7 hours and 9 hours per day.
Therefore , it is true.
<h3><u>Answer:- </u></h3>


<h3><u>Solution</u> :-</h3>

The unit of mass is kg and unit of Volume is m³ . Since density is division of mass by volume , the corresponding units will also get divided and unit of density would come out to be kg/m³
<u>Some basic </u><u>derived </u><u>Units :- </u>
- area => m²
- volume cubic meter => m3
- speed meter per second => m/s
- acceleration => m/s²
- mass density meter => kg/m3
- specific volume cubic meter per kilogram m³/kg
