Let P sub O, P sub 1, ..., P sub p be p1 normal populations with unknown population means u sub p and known population variances. P sub O is referred to as the control population and P sub i 1 less than or equal to i less than or equal to p as the ith test population. Based on N sub i independent observations X sub ij j1,2,..., N sub i from P sub i i0,1,...,p where N the sum over i from 0 to P of N sub i and constants r greater than or equal to 0, d0 are specified prior to experimentation, it is desired to make an exact confidence statement of the form 1 meanx sub O-meanx sub i-d u sub O - u sub i meanx sub O-mean x sub i rd i1,2,...,p where meanx sub i is the observed sample mean from P sub i.
