Which is the quadratic equation the best fits the scatterplot? We see that both temperature and temperature squared are significant predictors for the quadratic model (with p-values of 0.0009 and 0.0006, respectively) and that the fit is much better than for the linear fit.From this output, we see the estimated regression equation is \(y_{i}=7.960-0.1537x_{i}+0.001076x_{i}^{2}\). 1 0 obj The table below lists temperatures measured in Fahrenheit and Celsius. [Round the answer to the nearest tenth of a million.] In this method, we find out the value of a, b and c so that squared vertical distance between each given point (${x_i, y_i}$) and the parabola equation (${ y = ax^2 + bx + 2}$) is minimal.
