One subject not included in the given table had a PSAT score of 229. Find the best predicted SAT score for this student. Is the result close to the reported value of 2400? Given that the data are from volunteered responses, are the results valid?

Find the regression equation using α = 0.05, letting the first variable be the predictor (x) variable. Find the indicated predicted value by following the prediction procedure summarized in Figure.

The regression line graphed in the scatterplot shows that the line fits the points well . rindicates that there is a linear correlation. . The prediction is not much beyond the scope of the available sample data Yes. The regression equation is a good model No. The regression equation is not a good model. Substitute the given value of xinto the regression Regardless of the value of the best predicted value of y is the value of y (the mean of the yvalues) equation bothix
