You can put this solution on YOUR website! A vending machine dispenses coffee into an eight-ounces cup. The amounts of coffee dispensed into the cup are normally distributed with a standard deviation 0.01 ounce. You can allow the cup to overfill 1% of the time. What amount you should set as the mean amount of coffee to be dispensed?
---------------------------------------
Find the z-value with a right tail of 1%: z = 2.3263
-----------
Find the x-value using x = zs+u
x = 2.3263*0.01+8 = 8.0233
========
Let that be the mean amount of coffee to be dispensed.
