Question

A company did a quality check on all the packs of nuts it manufactured. Each pack of nuts is targeted to weigh 18.25 oz. A pack must weigh within 0.36 oz of the target weight to be accepted. What is the range of rejected masses, x, for the manufactured nuts?

Answer 1

The minimum accepted mass is 18.25 - 0.36 = 17.89 oz
The maximum accepted mass is 18.25 + 0.36 = 18.61 oz

So the range of rejected mass is x < 17.89 U x > 18.61
