## Chapter 12 - Day 8

##### Questions to be Sure to Include
• Integrate review questions into this test. This includes questions that ask students to

• use a model to make predictions

• calculate and interpret a residual

• interpret a residual plot

• interpret slope and y-intercept in context

• analyze residual plots

• interpret r and r-squared

• interpret s

• Questions that ask students to use regression computer output to:

• find a linear or nonlinear model of best fitâ€‹

• make a prediction

• calculate a confidence interval for slope

• perform a significance test for slope

• In the free response, consider using one context to have students do both a confidence interval and a significance test for slope. Provide students with regression computer outlet so that they have SEb. â€‹

##### Tips to Give Your Students
• Close reading and careful writing are critical to your success this year.

• Be sure to answer all parts of each question.

• There is a difference between a residual plot and a dotplot of residuals.

• Use the 4-step process for inference. At this point, you are well trained!

• Know your inverse transformations (log and natural log)
