Least- squares Regression: usually fits a straight line of the form
y^ a+ bx to data.
This is used to predict a response variable, y, from an
explanatory variable, x.
Inference in this setting uses the sample re

Chapter 9 Outline
A significance test is a formal procedure for comparing observed fats with a claim that
we wish to test.
The claim is a statement about a parameter.
