At the highest 1.5%

Z = 2.27  according to the Z chart for normal distribution

That means 2.27 standard deviations above the mean

(2.27)(.04) = 0.091 ounces more than 12.26

12.26 + 0.091 = 12.351 ounces or more

Oops, I read the chart wrong...it's Z = 2.17 not 2.27  (a little hard to line up the numbers on the chart)

So, then it's (2.17)(0.04) = 0.0868

12.26 + 0.0868 = 12.347
