Because of natural variability in manufacturing, a 12-ounce can of soda does not usually hold exactly 12 ounces of soda. A can is permitted to hold a little more or a little less. The specifications for the soda-filling machine are that it needs to fill each can with 12 ± 0.25 ounces of soda. If a can of soda is filled with 11.97 ounces of soda, is the filling machine operating within specifications? Homework Help ✎

Is 11.97 between 12 − 0.25 and 12 + 0.25?

Yes. As little as 11.75 ounces is still within specifications.
