Find the best predicted weight of a seal if the overhead width measured from a photograph is
Question:
Find the best predicted weight of a seal if the overhead width measured from a photograph is 2 cm. Can the prediction be correct? What is wrong with predicting the weight in this case?
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.
