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.

Watching TV: The general Social Survey asked a large number of people how much time they spent watching TV each day. The mean number of hours was 3.09 with a standard deviation of 2.93 . Assume that in a sample of 34 teenagers, the sample standard deviation of daily TV time is 4.1 hours, and that the population of TV watching times is normally distributed. Can you conclude that the population standard deviation of TV watching times for teenagers differs...
