Mean = sum of data/number of data pieces
numbers of hours of work per day = 6, 7, 8, 9, 10
sum of data / number of data pieces
6+7+8+9+10/5
40/5
8
The mean of the hours worked each day is 8.
Therefore Ryan is correct. Mean is the calculation of the sum of all the data divided by the number of data pieces. I added all the data together and got 40. There are 5 data pieces. So I divided 40 by 5 and got 8.
