Which distribution? Confidence Intervals & Hypothesis Tests
To estimate p or test a claim about p, use a z distribution Table A-2
To estimate μ or test a claim about μ, use a t distribution Table A-3

Techniques to be learned in Chapter 9: Based on sample statistics taken from two populations test a claim about the relationship between the population parameters using the method of Hypothesis Tests.
Use the formal procedures of hypothesis tests to make decisions about two populations.
9-1 Overview
The parameters to be considered for hypothesis tests are:
9-2 Inferences about two proportions p1 and p2
9-3 Inferences about two independent means μ1 and μ2
9-4 Inferences about the mean difference μd of matched pairs.
