You can choose to work some or all of the problems listed below. We recommend that you at least work the problems listed in your major area of interest. This is a good time to start practicing the use of the computer for helping with your data analysis. Most of this work can be easily accomplished in the Minitab and SPSS and Proc Insight in SAS. With a little practice this can also be easily done in SPlus and R. The graphs, like sidebyside Box Plots may be more difficult to construct in Excel or Quattro Pro. Exercise answers here.
General Questions 

For students in agriculture and environmental fields. 
Using the data from Problem 3.65, page 112 in Ott and Longnecker, compute the following statistics. The transmissivity values are transformed by first taking their natural (base e  ln) logarithms (you will need a calculator or computer for this). We will refer to this new (derived response) as the ln transmissivity.
With these statistics answer the following.

For students in engineering fields. 
Using the data from Problem 3.55, page 108 in Ott and Longnecker, compute the following statistics.
With these statistics, answer the following.

For students in toxicology and health science fields. 
In a study of the accumulation of polychlorinated biphenyls (PCBs) in humans after chronic environmental exposure, Patterson, et. el. (1994, Env.
