These problems are designed to provide you with practice for the hourly exams and final. You should do these problems only after you have had all the labs scheduled prior to the hourly and you have reviewed the material. Time yourself. Remember that on an hourly (Exam 1 and 2), you should allow about 8 minutes per problem. Try to do these problems in 8 min. Time is not such an issue on the Final, but you should be able to do the problems in 15 min.

These problems are designed for students in the BIO 211/L Biometrics class at California State Polytechnic University, Pomona. The course is an introductory course in applied, inferential, univariate statistical analysis for majors in Biology and related areas. The solutions for the problems are presented in the context of the course. It is true that, in many cases, there are other procedures that could be used for a particular problem. For example, it could be argued that any problem utilizing an analysis of variance or t statistic solution could be solved using a general linear models approach, with appropriate coding of dummy variables and calculation of regression quantities. It could further be argued that this would be a more general approach, and more closely reflect the method used by some major statistical computer packages (e.g. SAS). While this argument would prevail, this approach is well beyond the scope of this class. Nevertheless, I would appreciate any comments anyone may have on any of the problems.
