We’ll start off using a sample size of 100 and .4 to .6 boundary lines to make a 95% confidence interval for testing coins. Any coin whose proportion of heads lies outside the interval we’ll declare unfair.

WebbWe examine two types of problems to illustrate this. Unstructured testing problems arise typically (but not exclusively) when many outcomes are being measured. We consider the case of more than two hypotheses when a Bonferroni approach is being applied while for illustration we assume compound symmetry to hold for the correlation of all variables.
