The questions below relate to the work done in Lab 8. Give all numeric answers correct to 2 decimal places.

1. From Exercise 1 (a), does stations have a positive or negative relationship with the magnitude of the earthquake? Enter 1 for positive or 0 for negative.
2. From Exercise 1 (b), does depth have a positive or negative relationship with the magnitude of the earthquake? Enter 1 for positive or 0 for negative.
3. From Exercise 1 (c), set the seed to 404 and get the training and testing dataset. What is the magnitude value for the first observation in the training dataset?
4. From Exercise 1 (d) what is the coefficient for stations in model 1?
5. From Exercise 1 (d) what is the coefficient for stations in model 2?
6. From Exercise 1 (h), which model has a smaller mean absolute error. Enter 1 for model 1 or 0 for model 2.
