An industrial engineer is planning to test the claim that the mean cycle time of a particular assembly process is less than 10 minutes. She sets α = 0.05 and plans to take a SRS of 100 such processes and record the cycle time for each. If the true mean cycle time of the assembly process is 9.78 minutes the power of her test is 0.85. In all possible samples of size 100 she will:
