Abstract : In section 1 a number of problems relating to the ratio based on the expected length of time needed to observe the first r failures out of n items placed on the test (1 < or = r < or = n) and the expected length of time needed to observe all r failures of the sample placed on the test for various distributions (exponential, Weibull, uniform, Gamma, logistic, Pareto, Cauchy) are considered. In section 2 several interesting and useful properties of the Compound Weibull and related distributions are investigated. In section 3 power functions are derived for the KumarPatel test which are based on right censored samples for testing the equality of location parameters of two exponential distributions when their common scale parameter is unknown. In section 4 conditions under which a sequence of inequalities are valid are established, and some allied problems are discussed. (Modified author abstract)
