  1. Suppose you observed a number of different fires and you graph
  2. the number of firefighters versus the size of the fire.
  3. And for the sake of the argument, let's assume we studied four fires
  4. with 10, 40, 200, and 70 firefighters involved
  5. and the sizes of the fires were given as follows: 100, 400, 2000, and 700
  6. in terms of the surface area that the fire occupied.
  7. Putting this into a diagram, you get pretty much the following.
  8. Put the number of fighters. In fact, you've already learned this looks very linear.
  9. So, let me ask a question--is the number of the firefighters correlated with the size of the fire?
  10. Yes or no? Check one of the two boxes.
