Tonight's HW = Review for Quiz!

• Tonight please work on the "Confidence Intervals for Proportions: (Practice Quiz)" provided in class or linked below.
• CI for Proportions Practice Quiz! (click me so you can study!)
• This assignment is due on Friday. A key will be posted tomorrow.

(This past) Monday's HW (can be checked tomorrow for full credit):

• Pages 446-449:  7, 11ac, 23abc, 31a
• Note: for 23, a quiz question would only say "estimate the proportion of students nationwide who are only children." You would then have to know to do the conditions (a), math (b), and interpret the interval (c).

Extra Credit HW = extra practice for quiz! (due Friday):

• Pages 447-449:
• 9 (interpret interval)
• 13 (full interval process, interpret c. level, use interval to test a claim)
• 33 (finding sample size)
• 37 (find c. level)

Here's the plan for the rest of the week:

• Thurs (2/27): stamp + more classwork/practice for quiz!
• Friday (2/28): ch. 19 quiz = vocab MC, AP FR, and AP MC (full period quiz). Come ready.
• Monday (3/2): start ch. 20 --> hypothesis tests for proportions!
