To work out the mean of a data set add all the numbers together and divide them by the number of data items there are.
18 + 14 + 8 + 22 + 25 + 8 = 95
95/6 = 15.8 (that answer is rounded)
7.5 x 103 is the scientific notation of 7500
The answer is 75
how do i know?
1500 divided by 20
It should be 1x if i am right
