Read sections 2.12, 7.2 (portions dealing with sampling distributions of the sample mean for known and unknown variance), 7.3, and 7.5 in the text. Review the material covered in lecture.

Reminder: This assignment will not be collected. Its purpose is to help you review the material we have covered in class and the text, but it is not to be viewed as an exhaustive list of topics/skills that you need to know.

Chp. 7
7.2, 7.4 (p. 301); 7.20, 7.24 (p.307); 7.34, 7.40 (pp. 313-314)
Additional practice problem with the t distribution: Refer again to problem 7.1 on p. 301 of your text. How would you solve the problem if you didn't know the standard deviation, and instead you only knew the sample standard deviation s=4?
