Question: For the regression equation in Exercise 16 47 the estimated number
For the regression equation in Exercise 16.47, the estimated number of persons swimming on a zero-degree weekday would be 100 persons. Since this level of pool attendance is unlikely on such a day, does this mean that an error was made in constructing the regression equation? Explain.
