Abstract : The tables give values of the probability density and cumulative distribution functions of the random variable alpha sub 1 (U sub 1 squared) + alpha sub 2 (U sub 2 squared) + alpha sub 3 (U sub 3 squared) + alpha sub 4 (U sub 4 squared) + alpha sub 5 (U sub 5 squared) where the U's are mutually independent unit normal variables, with the alpha's satisfying the condition alpha sub 1 + alpha sub 2 + alpha sub 3 + alpha sub 4 + alpha sub 5 = 5. The tables include sets of alpha values from (3.0, 0.5, 0.5, 0.5, 0.5) to (1.1, 1.1, 1.0, 0.9, 0.9) in all seventy sets of alpha values. The tabulated values, shown to five decimal places, are based on original calculations which should have an error less than 1 in the eighth decimal place.
