5. Rounded to three decimal places, what is the value of r for this data set?
IrinaVladis [17]

The value of correlation coefficient (r) for the dataset is 0.981

<h3>What is correlation coefficient (r)?</h3>

The correlation coefficient (r) is used to determine the closeness and association of a scatter plot points.

The dataset is given as:

  • x: 8  15  3  7  2  14
  • y: 15  21  6  12  3  20

Using a graphing calculator, we have the following parameters:

<h3>X Values </h3>
  • ∑x = 49
  • Mean = 8.167
  • ∑(X - Mx)2 = SSx = 146.833

<h3>Y Values </h3>
  • ∑y = 77
  • Mean = 12.833
  • ∑(Y - My)2 = SSy = 266.833

<h3>X and Y Combined </h3>
  • N = 6
  • ∑(X - Mx)(Y - My) = 194.167

The correlation coefficient (r) is then calculated as:

r = \frac{\sum{((x - My)(Y - Mx)) }}{ \sqrt{((SSx)(SSy))}}

This gives

r = \frac{194.167 }{ \sqrt{((146.833)(266.833))}}\\

r = 0.9809

Approximate

r = 0.981

Hence, the value of correlation coefficient (r) for the dataset is 0.981

A) -9

-7(x+9)=9(x-5)-14x
-7x-63=9x-45-14x
-45 -45
-7x-18=9x-14x
+7x +7x
-18=9x+7x-14x
-18=2x
(-18)/2=(2x)/2
