Deals with comparison of a mean with a given value (variance known or unknown), of two means (variance known or unknown), of a variance with a given value, and of two variances, and gives sets of curves for these type II risk for a given alternative and given size of sample and to determine the size of sample to be selected for a given alternative and a given values of type II risk.
