Question

The mean number of hours that Raphael worked over the past four weeks is 35.75. if he works 37 hours this week, what will the mean number of hours be that he will have worked over the five week period? what is the five week mean? __________

Answer 1

Okay, here we have this:

Considering the provided information we obtain the following:

Mean of the five week period=((Mean of the past four weeks*4)+Hours worked this week)/5

Replacing:

Mean of the five week period=((35.75*4)+37)/5

Mean of the five week period=(143+37)/5

Mean of the five week period=180/5

Mean of the five week period=36

Finally we obtain that the five week mean is 36 hours.
