What is the least squares regression line equation ?

y = 4.554120007 + (-0.13415474)X + u

Where u just represents the unobserved variation (you probably don't really need to put it).

Y and X are your dependent and independent variables. Just based on the name of the tabs in Excel I assume they are Benefits and Intrinsic, respectively

What are the slope and the y-intercept?

Slope = -.134
Intercept = 4.55

What is the R-squared value?

0.043361731 ...

Solution Summary

The least squares regression line equation is defined in the solution. The slope and y-intercept are determined. The solution provides conclusions and comments regarding any similarities and differences in the output results.
