Weekend HW!

No AP problems this weekend....

Please complete the worksheet provided in class--a recap of many of the things we've learned so far in chapter 8.

• If you were absent or lost yours, the homework can be downloaded under our classroom resources, entitled, "Ch. 8 Recap: Weekend HW!"
• For those of you who told me you'd be absent, the 2 worksheets I gave you are the weekend homework (talk to your classmates for some help!)

What did we do today in class?

• Stamp problem--Is a linear model appropriate?
• We reviewed/recapped how to answer this question and how to create residual plots on our graphing calculator.
• We also discussed how to sketch a residual plot from a graph, or how to sketch a graph given a residual plot
• We then made a list of "what we need to know" for chapter 8
• We discussed how to interpret y-intercept (next comes slope and R^2)

See you all on Monday! You'll start with a two question quiz when you walk in....be ready! These will be the questions...

1. Is a linear model appropriate?
2. Find the regression equation. Define the variables.
