I have been made aware ¡­

I have been made aware of a misprint in exercise 1 of the project exam. The misprint have no influence on how the exercise should be solved, but nevertheless, VOLUME is measured in cubic feet (not square feet). I have also been made aware of a misprint in exercise 4 (again of no importance for solving the exercise), where SEX should be coded 1 and 2 (not 0 and 1).
