Iwish to determine the correlation between the height (in inches) and weight (in pounds) of 21-year-old males. to do this, i measure the height and weight of two 21-year-old men. the measured values are height and weight of male 1: 70, 169 height and weight of male 2: 69,164 the correlation r computed from the measurements on these males is question 2 options: 1.0 -1.0 near 0 because the heights and weights of the men are similar.

![r=\frac{2(23146)-(139)(333)}{\sqrt{[2(9661) -(139)^2][2(55457) -(333)^2]}}=1](/tpl/images/0469/2591/bfef5.png)
![r=\frac{n(\sum xy)-(\sum x)(\sum y)}{\sqrt{[n\sum x^2 -(\sum x)^2][n\sum y^2 -(\sum y)^2]}}](/tpl/images/0469/2591/ec454.png)
