A company manufactures 16 -oz boxes of cereal. Boxes are randomly weighted to ensure the correct amount. If the discrepancy in weight is more than 0 point 1 5 oz, the production is stopped. What is the range of acceptable values for production to continue?
Answer
A
15 point 1 5 oz to 16 point 0 0 oz
B
15 point 8 5 oz to 16 point 0 0 oz
C
16 point 1 5 oz to 16 point 4 5 oz
D
15 point 8 5 oz to 16 point 1 5 oz
Explanation
The acceptable discrepancy is at most 0.15 oz from the target weight of 16 oz. Subtract and add 0.15: 16 − 0.15 = 15.85 oz and 16 + 0.15 = 16.15 oz. So production can continue for boxes weighing 15.85 oz to 16.15 oz, which is choice D.
