Question: Construct a scatter plot using excel for the given data. Determine whether there is a positive linear correlation, negative linear correlation, or no linear correlation. Complete the table and find the correlation coefficient r.

The data for x and y is shown below.

x -5 -3 4 1 -1 -2 0 2 3 -4
y 11 -6 8 -3 -2 1 5 -5 6 7

a) Scatter plot (3 points)

b) Type of correlation (positive linear correlation, negative linear correlation, or no linear correlation) (2 points)

c) Complete the table and find the correlation coefficient r rounded to 4 decimals.

(5 points)

x y xy x2 y2
-5 11
-3 -6
4 8
1 -3
-1 -2
-2 1
0 5
2 -5

-4 7

Use the last row of the table to show the column totals.

n = 10

\[r=\frac{n\sum{xy-\left( \sum{x} \right)\left( \sum{y} \right)}}{\sqrt{n\sum{{{x}^{2}}-{{\left( \sum{x} \right)}^{2}}}}\sqrt{n\sum{{{y}^{2}}-{{\left( \sum{y} \right)}^{2}}}}}\] =
