11-77.

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 $12\pm0.25$ ounces of soda. If a can of soda is filled with $11.97$ ounces of soda, is the filling machine operating within specifications?

Is $11.97$ between $12-0.25$ and $12+0.25?$
