Chapter 14 - The final frontier

Inferences for regression

HW for Monday: Entire free response test from 2004. Take 90 minutes under test conditions.

HW for Friday: Problem 6 from 2007 AP exam.

HW due Thursday: Problems 14.11 and 14.18 PLUS the chapter summary.

HW due Wednesday: Problem 2 from the 2006 exam. Language is critical. If you do not know what the question asks, look at Example 14.5 in the text. Respond IN CONTEXT. There will be no partial credit for this problem.

DO NOT FORGET that your one-page summary of the selected chapter is due Thursday.

This chapter explains how to use the slope of a LSRL calculated from a sample and the std dev of the slopes




  1. to create a confidence interval for capturing the slope of the true equation through ALL the data and
  2. to make decisions about a hypothesized linear relationship.
Your calculator will do most of the number crunching. Investigate the LinRegT-Test function in the STAT TESTS area.

Why are there only n-2 degrees of freedom?
Why do we make such a big deal about s sub-b1 being the std dev of the slopes?

HW for Tuesday: problems 14.1 and 14.2 from the text.

Chapter summary due Thursday.

i signed up to take the practice test tomorrow after school, but i just realized that i have my last track practice/meeting tomorrow right after school. when i signed up, i was thinking that i wouldn't have track at all this week because we just had our last meet. i'm really sorry - i made a mistake. is there any way i can change to a different day?
