Step 2

Data Set A

x	1	2	3	4	5	6	7
y	7	7	7	9	9	9	10

Data Set B

x	1	2	3	4	5	6	7	8	9	10	11
y	4	6	6	6	8	9	9	9	10	10	10

Step 2

Find the equation for the least-squares line, and graph the line on the scatter plot.
Find the sample correlation coefficient r and the coefficient of determination r². Is r significant? What criteria did you use to determine if it was significant? For each set of data
What predictions can you make using this data sets? Write a brief explanation of what you found in the data sets.
