Using the following data withxas the independent variable andyas the dependent variable, answer the items.

x -26 -34 30 20 36

y 76 265 171 21 359

a.make a scatter diagram.

1. On the graph below, use the point tool to plot the point corresponding to the first point and second point (Point 1).

2. Repeat the process for the remainder of the sample (Point 2, Point 3, ... ).

3. To enter exact coordinates, double-click on the point and enter the exact coordinates of x and y.

b.Compute the correlation coefficient.(Round your answer to 4 decimal places.)

c & d.Transform thexvariable by squaring each value, x², and make a scatter diagram.

1. On the graph below, use the point tool to plot the point corresponding to the first point and second point (Point 1).

2. Repeat the process for the remainder of the sample (Point 2, Point 3, ... ).

3. To enter exact coordinates, double-click on the point and enter the exact coordinates of x and y.

e.Compute the correlation coefficient between x² and y.(Round your answer to 4 decimal places.)
