Math 325, Fall 2011, Garren

Exercises followed by a "*" are due by the due date. All other exercises are recommended but not required.

Exercises followed by a "$" need to be solved twice, once using macros from library(survey) and once without those macros.

Do NOT use calculators. The only software permitted is R.

Whenever you use R to solve the exercises, print both the source code and the computer's answer, and clearly label these.
