During his lunch hour, Matt asked 24 students how many after-school activities they participated in. This list shows the survey results.
Results: 1,2,0,0,3, 2, 4, 2, 1, 4, 3, 2,
1,1,2,1,0,3,3, 2, 4, 1, 1, 0
What is the ratio of the number of students not participating in an activity to the total number of students surveyed?
What can you infer from this data?

As you can see, 4 of the 24 students don't partecipate in any activity. This clearly implies a ratio of 4:24, or 1:6.

We could infer that this ratio holds for the whole school, or even for all the boys and girls of that age.

That's the point of surveys and inferring: you gather data about a relatively small group, and then assume that the proportions you have are valid for a much larger group.

That's why it is important that the group that you survey is balanced and unbiased.

point a is the center of the circle that passes through points e, f, and g and the center of the circle that passes through points x, y, and z.
