Testing One-sided Fuzzy Hypotheses For The Parameter Of Normal Distribution

Recent years,many scholars have shown interests in the research of the fuzzy hypotheses.In this paper we mainly discuss the testing one-sided fuzzy hypotheses for the parameter of normal distribution.As in[7],author Bernhard F.Arnold have discussed the testing expectation with known variance,this paper mainly contains the other three cases:testing expectation with unknown variance,testing variance with known expectation,testing variance with unknown expectation.And our investigated approach is familiar with the general approach which tests via constructing a statistical testing and fixing the probabilities of the errors of typeâ… andâ…¡.
