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?\n42.668 mm to 42.670 mm\n42.668 mm to 42.672 mm\n42.670 mm to 42.672 mm\n42.670 mm to 42.674 mm
Answer
Explanation:
Step1: Find the lower - bound
Subtract the maximum discrepancy from the standard diameter. The standard diameter is $d = 42.67$ mm and the maximum discrepancy is $\Delta d=0.002$ mm. The lower - bound is $42.67 - 0.002=42.668$ mm.
Step2: Find the upper - bound
Add the maximum discrepancy to the standard diameter. The upper - bound is $42.67+ 0.002 = 42.672$ mm.
Answer:
42.668 mm to 42.672 mm
