We cannot use the least-squares regression line to predict y from x. In these situations, statisticians often try to manipulate one or both of the variables to try to find a linear fit. This is called transforming the variables. For each data point, compute the cube of the wind speed to obtain x3, then compute the least-squares regression line for predicting power y from x3.
