The true amount of sparkling water in a can should be 12 pinches, with a standard deviation of 0.5 ounce. We purchase a 36-pack of sparkling water and find the mean amount of the liquid per can is only 11.79 ounces. If we were trying to buy a 36-pack of sparkling water that was at the 80th percentiles in terms of how much liquid it has, what mean amount of liquid per can would this 36-pack have?
