Answer:

250.9

Step-by-step explanation:

Find mean by adding all the terms and dividing by the number of terms.

173+299+181+103+540+81+270+360=2007

We divide by 8 since we are adding 8 different numbers.

2007/8 =250.875

We round this number. We want to round the 250.875 depending on the number that follow the 8. The number after 8 is 7, 250.875. Since seven is above five, the 8 will increase to a 9. So we have:

250.9
