6.4 Predicting Prices of Used Cars. The file ToyotaCorolla.csv contains data on used cars (Toyota Corolla) on sale during late s
Brums [2.3K]

Answer:

Compare the predictions in terms of the predictors that were used, the magnitude of the difference between the two predictions, and the advantages and disadvantages of the two methods.

Our predictions for the two models were very simmilar. A difference of $32.78 (less than 1% of the total price of the car) is statistically insignificant in this case. Our binned model returned a whole number while the full model returned a more “accurate” price, but ultimately it is a wash. Both models had comparable accuracy, but the full regression seemed to be better trained. If we wanted to use the binned model I would suggest creating smaller bin ranges to prevent underfitting the model.

Consider the following code: public static void mystery(int a) { System.out.println("A"); } public static void mystery(double a)
Feliz [49]

Answer:

The output is "A"

Explanation:

public class Solution {

   public static void main(String args[]) {

     mystery(7);

   }    

   public static void mystery(int a) { System.out.println("A"); }    

   public static void mystery(double a) { System.out.println("B"); }    

   public static void mystery(int a, double b) { System.out.println("C"); }    

   public static void mystery(double a, int b) { System.out.println("D"); }

}

In the code above; mystery is defined in four different ways called method overloading. Method overloading is when same method is defined with different parameters.

In the first case; mystery will be called if the argument is int.

In the second case; mystery will be called if the argument is double.

In the third case; mystery will be called if the arguments are int and double.

In the fourth case; mystery will be called if the arguments are double and int.

When mystery(7) is called; the mystery method requiring only int will be called and the output is "A".
