Lecture 7: Any confidence interval or significance test can be trusted under specific conditions. Simple conditions are: SRS 2. Normal population distribution Known σ Any inference procedure based on sample statistics like the sample mean x that are not resistant to outliers can be strongly influenced by a few extreme observations. ¿√n Confidence intervals have margin of error MOE=z The margin of error will be made smaller by: lowering the confidence level which makes z ∗ smaller σ being smaller (we have no control over this) increasing the sample size so n is larger The margin of error covers random sampling errors. It does not take into account other difficulties such as un
