Table:

x: 6, 2, 15, 9, 12, 5, 8

y: 8, 9, 4, 7, 6, 9, 8

1) Make the scatter diagram.

2) Find the equation of the regression line using the formulas given in class. They must appear the intermediate steps of substitutions. Round the answers to three decimal places.

3) Find the correlation coefficient using the formulas given in class. Steps should appear intermediates of substitutions. Round the answer to three decimal places.

4) Find the value predicted by the regression line equation for x = 9. Explain the reason for the difference between the observed y value and the estimated y value.

5) Calculate the SSE.
