Math 207 Homework Assignment 6

Due Friday, November 5 (beginning of class)

REMINDER: As mentioned on previous homework assignments, I expect your homework solutions to be thorough, well-written (use context and complete sentences), neat, complete (thoughtfully answer all parts of the question), stapled, and in your own words/explanations (re: Honor Code).

IMPORTANT NOTES:

• Be sure to explicitly do appropriate sample-size checks before you use a large-sample confidence interval or significance test.

• Be sure (when asked) to not only determine the confidence interval, but also to appropriately and thoroughly interpret the interval in words.

Textbook Problems:

8.33

8.35 (part b asks for ways to reduce the width of the confidence interval)

8.36

8.44

8.58

8.74 (use a 95% confidence level)

8.77 (use a 99% confidence level)

8.81
