To find the correlation coefficient for the set of data, follow these steps:
1. Enter the years in List1 in your calculator and the corresponding heights in List2.
2. Go to the stat menu on your calculator and select "Edit" (or any similar option).
3. Enter the years in List1 and the heights in List2.
4. Go to the stat menu again and select "CALC" (or any similar option).
5. Choose "LinReg" or "LinReg(ax+b)" (linear regression) and press enter.
6. The calculator will output the equation of the line of best fit and the correlation coefficient (r).
The correlation coefficient for this set of data is 0.989.
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?
