ABSTRACT
The general principle in scientific experiments is to formulate a mean ingful hypothesis (i.e., statement) and then test it or verify it. A statistical hypothesis is a statement either about the values of one or more of the pa rameters of a given distribution or about the form of the distribution itself (Afifi and Azen, 1972). For this purpose, investigators should collect suffi cient data from well-designed and well-executed experiments. The purpose of the design is to provide the experimenter sufficient data for testing of the hypothesis. We are therefore generally concerned with testing the validity of the hypothesis.
