Answer to Problem 16HP
A regression line gives the accurate result. And, an accurate line of fit can never give the prediction what will happen in future.
Explanation of Solution
Given information:A scatter plot and a line of fit for predictions.
Calculation: A scatter plot is usually used to predict whether there is a relationship between the given two quantities. It just gives the accurate prediction, but not the accurate result for the given set of two quantities. There are useful if scatter plot and actual line of fit gives accurate prediction. And in order to get the accurate prediction regression line is used. Even line of best fit cannot give the accurate result.
Hence, an accurate line of fit cannot predict what will happen in future.
