(Round to two decimal places as needed.) Part 3 Interpret the standard error. Choose the correct answer below. A. The standard error is the percent of variation explained by the multiple regression model. B. The standard error is the expected error of the predicted sales given a specific total square footage and number of shopping centers. Your answer is correct.C. The standard error is the sum of unexplained error in the multiple regression model. D. The standard error is the average predicted sales for the multiple regression model.
