Math 325, Fall 2023, 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 functions from "survey" package and once without those functions.

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.

Read in (i.e., do not retype) the data, whenever the data are available on my website.

Highlight the exercise numbers and your final answers (unless your final answer is a large table), and submit .pdf or .html file using Canvas.
