To model some data, Anne ran a linear regression and found the regressionequation to be y 0.554x-0.507.The scatterplot and residual plot are shown.ScatterplotResidual plot Select the true statements.A The model is not a good fit because there is a pattern in theresidual plot.B. The residual plot changes direction, so a quadratic model wouldfit the data better.AC. The points in the scatterplot increase quickly, so an exponentialmodel would fit the data better.D. The model is a good fit because the patterns in the plots are bothcurves,

In this case, the independent variable is x and the dependent variable is y.

Answered: Select the true statements. A. The…
