Question $3$

Lay's makes potato chip bags that need to be between $99\mathrm{.}5oz$ and $100\mathrm{.}5oz.$ You do measurements,

and you find that a normal distribution describes Lay's actual bagging machine performance.

Specifically, the mean of the process is $99\mathrm{.}55oz,$ and the process standard deviation is $0\mathrm{.}08oz.$ If

Lay's wants to achieve "six sigma" quality, 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 $-84\mathrm{.}344\%,$ enter $-83$ into the box.
