On a test of independent samples, Power = .90, Effect Size = .8, and Alpha = .05. The minimum number of samples needed for the entire test would be: (a) 27 (b) 54 (c) 68 (d) 48 Note: Some tutor previously answered this question on Course Hero. I unlocked the answer but it was 16, which is not one of the choices. I wasted an unlock for it. Please help to solve this
