Lay's makes potato chip bags that need to be between 99.50z and 100.5oz. You do measurements, and you find that a normal distribution describes Lay's actual bagging machine performance. Specifically, the mean of the process is 99.55oz, and the process standard deviation is 0.08oz. If Lay's wants to be within the tolerances 99.7% of the time, by what percentage. does Lay's need to change the process's standard deviation by? Round your answer to the nearest percentage, and answer without the percent symbol. For example, if your answer is 84.344%, enter -83 into the box
