Abstract (2. Language): 
In this paper, we employed the series expansion of incomplete gamma function via the Taylor series to obtain the function for pivotal quantity from which the confidence intervals for each parameter of a special family of elliptically contoured distribution called the exponential power distribution (EPD) were derived. The results obtained were further used to determine the estimated sample size when sampling from EPD as well as the pivotal test statistic for the test of mean differences between two independent EPD samples. Psychiatric screening instruments were used to demonstrate the applicability of the results.
