A 1 pound box of crackers should contain at least 16 ounces of crackers. To help ensure that each box satisfies this requirement, the manufacturer sets the filling machine to put an avera ge of 16.1 ounces with a standard deviation of .1 ounce. What percent of the boxes will weigh 15.9 ounces or less

Need to know how many crackers there are in the box. or the average weight of each cracker to determine the proper answer.
example if the crackers weight 0.1 oz then odd are close to zero
does the machine measure the box content, or count the crackers?
statically, depending on how the work is done, some box's may have more crackers than others.
But that's not you answer.

Assuming a normal distribution, about 95% of the boxes will weigh between 15.9 and 16.3 ounces, which is the average ± two standard deviations. So 5% will be outside this range, that is 2.5% at 16.3 ounces or more and 2.5% at 15.9 ounces or less.

if the deviation is only .1 package= 16.1
wouldnt the answer be 0%

None. They'll all weigh between 16.0 oz orand between 16.2 oz. in that range.
