=Problem 4.1:If we know the measurement of arm span, do you think we can know that person's height? To answer this question, collect the data that shows arm span and height of your class student and make a coordinate graph of that data.=

I think it's wrong because there are only few people who have almost same measurement on height and arm span.

=Problem4.1 follow up: draw a diagonal line at the graph where the two measure are the same measure.= 1.how many are in the line? compare the arm span and height of people on the line. answer- there are two people who are on the line and they have same height and arm span.

2.compare the arm span and height of people who are below the line. answer- they have shorter arm span and longer height.

3, compare the arm span and height of people who are above the line. answer-they have shorter height and longer arm span.
