Finding the Least Squares Regression Line In Exercises 89 and 90, find the least squares regression line for the points. Use the regression capabilities of a graphing utility to verify your results. Use the graphing utility to plot the points and graph the regression line.
To calculate: The least squares regression line for the data points
Given: The data points
Formula used: The line
Calculation: For the provided data points:
x | Y | xy | |
0 | 10 | 0 | 0 |
2 | 8 | 16 | 4 |
4 | 7 | 28 | 16 |
7 | 5 | 35 | 49 |
9 | 3 | 27 | 81 |
12 | 0 | 0 | 144 |
