A random sample of 25 bearings is selected, and average inside diameter of these bearings is 1.4975 inches. Bearing diameter is known to be normally distributed with standard deviation 0.01 inch. What sample size is needed to detect a true mean diameter as low as 1.495 inches instead of 1.5 inches if you wanted the power of the test to be at least 0.92? (alpha=0.01)
