2. Suppose that we assume the population standard deviation is σ = = 50 .5and we are testing: Ηο:μ Hа: μ > 50 Suppose also that we want the following Powers (probability of detection): = Power (MALT 50.25) = .90 Power (μALT = 50.40) = .95 2a) How much data is needed to satisfy the first requirement? 2b) How much data is needed to satisfy the second requirement? 2c) How much data is needed to satisfy both requirements?
