Question Answered step-by-step The diameter of 4.5-inch discs is normally distributed…. The diameter of 4.5-inch discs is normally distributed. Periodically, quality control inspectors at DooWap Discs randomly select a sample of nine diskettes. If the mean diameter of the discs is too large or too small, the disc punch is shut down for adjustment; otherwise, the punching process continues. Experience shows that the population standard deviation is 0.06 inches. H0: µ = 4.5HA: µ ≠ 4.5a. Assuming that α = 0.05, what is the power of the test when the mean diameter of the manufactured disc is 4.55 inches? Identify the decision rule in the context of the sample statistic ( ̅).
