4 Examples of Using Linear Regression in Real Life - Statology
Most of the “real world” relationships we have discussed so far have been linear. In many examples you were told that the relationship was linear and then were asked to construct the equation for the line, and hence the linear relationship, based on two points.

a) Find the least squares regression line. State the equation below and interpret the slope and y-intercept. b) Find and interpret the value of r2. c) Create a residual plot on your calculator. What does this plot tell you about a linear model for this data? How do you know? d) Find and interpret the residual for 93°.
