Brain$-$Grain produces bags of a mixture of grains that purportedly have health benefits. Each bag of grains is labelled to have $16$oz of the mixture. The packaging process is deemed to be working within specifications as long as bags that contain $15\mathrm{.}87$ to $16\mathrm{.}12$ oz$.$ The amount of the mixture filled in a bag by the packaging process has been found to be normally distributed with a mean of $16$ oz and a standard deviation of $0\mathrm{.}05$ oz$.$
