6 people were asked about the time in a week they spend in doing social work in their community.

6 people were asked about the time in a week they spend in doing social work in their community. They said 6, 19, 10, 5, 12, 10 hours, respectively. Calculate the average time (or mean time) in a week spent by them in social work. 

Solutions

Expert Solution

 

FORMULA OF THE MEAN - 

Mean = Sum of all the observation / Total number of observations. 

In our problem,

 Total number of observations = 6

(Since 6 people has been asked about the social work). 

And, also

Sum of all the observations = 6+19++10+5+12+10 = 62

Now, substitute these values in the formula of the mean we get, 

Mean = 62/6

Mean = 10.33


Hence, the average time spent by them in social work in a week is 10.33.
