Chapter 3 Standard units tell you how many standard deviations above or below average a data value is standard units = (actual value – average)/SD actual value = average + (SD x standard units). Standard units are denoted by Z.

Chapter 23 Inference About Means Copyright © 2010 Pearson Education‚ Inc. Getting Started n n n Now that we know how to create confidence intervals and test hypotheses about proportions‚ it’d be nice to be able to do the same for means. Just as we did before‚ we will base both our confidence interval and our hypothesis test on the sampling distribution model. The Central Limit Theorem told us that the sampling distribution model for means is Normal s with mean μ and standard deviation
