For questions 3–4, use your calculator to create a scatter plot and line of best fit for the following set of data:
Average height of a species of tree (in feet) after a certain number of years
Years 1 2 3 4 5 6 7 8
Height 2.1 3.2 6.8 7.3 11.2 12.6 13.4 15.9
What is the correlation coefficient for the set of data? Round your answer to the nearest thousandth.
