Abstract: The problem of fixed-width confidence interval estimation of the common mean of several normal populations having unknown and unequal variances is considered. A two-stage procedure is developed to tackle the problem and its nice asymptotic properties are studied.

Keywords: Fixed-width confidence interval, two-stage procedure, second order approximations
