Is the following residual plot a good fit for the linear regression? Why or why not?

Answer 1

Without seeing the residual plot, it is impossible to determine if the linear regression is a good fit. Residual plots are used to analyze the residuals of a regression model to see if they are randomly distributed around zero. If the residuals are randomly distributed with no clear pattern, then the linear regression is a good fit. However, if there is a clear pattern or systematic deviation in the residual plot, it indicates that the linear regression is not capturing the underlying relationship between the variables effectively.
