What is linear regression?

Here, the estimated simple linear regression equation to predict the repair time is Time = 3.45 + 0.617type.
The value of R² is 0.087. This illustrates that the type of repair is not a good predictor of the repair time.
Also, the estimated simple linear regression equation to predict the repair time given the repairperson is Time = 4.62 - 1.60person. It can be concluded that the tye of repair and time is positively correlated.
