Abstract SenGupta and Pal (1991,J. Statist. Plann. Inference,29, 145–155) have recently obtained the locally optimal test for zero intraclass correlation coefficient in symmetric multivariate normal mixtures, with known mixing proportion, for the case when the common mean,m, and the common variance, σ2, are known. Here, we establish that even under the general situation, when some or none ofm and σ2 are known, simple optimal tests can be derived, which are locally most powerful similar, whose exact cut-off points are already available and which retain all the previous optimality properties, e.g. unbiasedness, monotonicity and consistency. Some power tables are presented to demonstrate the favorable performances of these tests.
