 Handout (Continuous Random Variables): 1, 2, 3, 4, 5, 6, 7, 8

 Chapter 11: 25, 27, 29, 41cd, 45

Homework 7 (Due Wed, May 22 at 11:00 pm)

 Chapter 19: 11, 13, 15, 21, 23, 35, 41
Reading: Chapters 18 and 19. Note: for hypothesis testing problems, you must show how you calculated your test statistic. You do not need to show work for the step of going from the test statistic to the pvalue, as this step comes from tables or a calculator. You should always write a concluding sentence in which you explain your conclusion in the context of the problem. 

Homework 8 (Due Wed, May 29 at 11:00 pm)
 Chapter 20: 15, 17, 19, 23, 25, 27, 41
 Chapter 21: 15, 17, 19, 37, 39
Reading: Chapters 20 and 21. Note: for hypothesis testing problems, you must show how you calculated your test statistic. You do not need to show work for the step of going from the test statistic to the pvalue, as this step comes from tables or a calculator. If you are using tables rather than a calculator, it is OK just to report an interval containing the pvalue. You should always write a concluding sentence in which you explain your conclusion in the context of the problem. 

Homework 9 (Due Wed, Jun 5 at 11:00 pm)
 Chapter 22: 57, 59, 68, 72

 Chapter 24: 11, 13, 15, 19, 39, 41, 47
Reading: Chapter 25 (but you can skip 25.7 on "Logistic Regression") and Chapter 24.
