If vou seek help needlessly, either from your professor, a classmate, the solutions manual, or the math lab, you will not gain the maximum benefit from your work. It takes exercise, you know, to become strong. You cannot learn statistics through someone else's exercise. However, you must ask questions when necessary. Sometimes little things cause considerable confusion.

You will have to use good common sense in this matter. Many of the finer points. You must pay careful attention to these activities in order to really understand what is going on. Do not become frustrated if a topic or problem may completely baffle you at first.
