The standard diameter of a golf ball is 42.67 mm. A golf ball factory does quality control on the balls it manufactures. Golf balls are randomly measured to ensure the correct size. One day, an inspector decides to stop production if the discrepancy in diameter is more than 0.002 mm. What is the range of acceptable values?
The acceptable diameter is within 0.002 mm of the standard 42.67 mm. Subtracting and adding 0.002 gives 42.668 mm to 42.672 mm, so the correct choice is B, 42.668 mm to 42.672 mm.
