Question

Some people were asked how long it takes them to commute to work: 16 min, 5 min, 7 min, 8 min, 14 min, 12 min, 0.5 hr, 1 hr. What is the mean number of minutes?

Answer 1

Answer:

The mean number of minutes is;

$19\text{ minutes}$

Explanation:

Given the data;

$16min,5min,7min,8min,14min,12min,0.5hr,1hr.$

Firstly, let us convert all the data to the same unit (minutes);

$\begin{gathered} 16min,5min,7min,8min,14min,12min,0.5(60\min ),1(60\min ). \\ 16min,5min,7min,8min,14min,12min,30\min ,60\min . \end{gathered}$

We can now calculate the mean;

$\begin{gathered} \operatorname{mean}=\frac{\text{ Sum of all the data}}{\text{ number of data}} \\ \operatorname{mean}=\frac{16+5+7+8+14+12+30+60}{8} \\ \operatorname{mean}=\frac{152}{8} \\ \operatorname{mean}=19 \end{gathered}$

Therefore, the mean number of minutes is;

$19\text{ minutes}$
