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.

So then the we have perfect linear association.  Because the heights and weights of the men are similar.

Step-by-step explanation:

Let X represent the Height and Y the weigth

We have the follwoing dataset:

X: 70, 69

Y: 169, 164

n=2

The correlation coefficient is a "statistical measure that calculates the strength of the relationship between the relative movements of two variables". It's denoted by r and its always between -1 and 1.  

And in order to calculate the correlation coefficient we can use this formula:  

For our case we have this:  

n=2  

And if we replace in the formula we got:

So then the we have perfect linear association.  Because the heights and weights of the men are similar.

-362

step-by-step explanation:

(12)(4)+2(12)-34(12)+2(12)-3

  \/         \/         \/         \/

  48 +   24 -   408 + 24 - 3

      \   /               \   /

          72     -     432 - 3 = -363
