I think that this is a very hard question. There are a lot of answers but I came up with this conclusion. I think that if you know a person's arm span, then you probably know that their height is maybe a few centimeters near their arm span. I say this because looking at the data, most of the heights are about 1 or 2 centimeters under or above more of the arm spans. Most of the data is bunched up in one place, so it is a lot of times a close call when you want to see how close a Math 6E student's arm span is to their height. But overall, I think that a safe conclusion with evidence from the coordinate graph data would be that if you know a person's arm span, you might get a pretty good guess about what their height would be by guessing that it's probably a few centimeters above or under their arm spans.

__Problem 4.1 Follow Up: Find the data points in the coordinate graph where the measures for the arm span is the same as the height and draw a diagonal line through it. Describe the data points on, below and above the line. Page 44 DAU__




 * 1) No one from my class falls on this line although some people are very close. I notice that some people are almost perfect. The people that are very close to the line have longer arms than their height by a centimeter or two.
 * 2) The people that fall below the line are compared to monkeys and are like monkeys because their armspans are longer than there height. The majority of the class fall on this half of the coordinate graph as their armspans are longer than their heights taller.
 * 3) The people that fall above the line are tall and their armspans are shorter than their height. There are only 3 out of 18 people who fall on this half of the coordinate graph.
