Please help me 

 

Two groups of students were asked how far they lived from their school. The table below shows the distances in miles:

Group A (distance in miles) 1 1.5 8 9.2 6.8 4.5 4.8 2.5 0.76
Group B (distance in miles) 2 2.5 3.23 1.3 1.8 2.4 3 1.5 1.8


Which statement best compares the mean distances for the two groups?

It is equal for Group A and Group B.
It is greater for Group B than Group A.
Its value for Group A is double the value for Group B.
Its value for Group B is three times the value for Group A.

Add up all the numbers: 1+1.5+8+9.2+6.8+4.5+4.8+2.5+0.76= 39.06 and divide by how many numbers there are: 39.06/9=4.34

Group A= 4.34

Group B= 2.17

So, Group A is double the value for Group B. You are correct! Great job~
