Abstract
The exact formula for the variance of the uniformly minimum variance u nbiased estimator (UMVUE) of the reliability function, R(t), for expon ential life is quite cumbersome. A simple expression for the asymptoti c variance of the UMVUE of R(t) is found. Interval estimates of R(t) a re also constructed. By comparing the approximations to the exact valu es in several configuration of sample size and population parameter, t he derived formula is shown to be useful for sample sizes larger than 15.
