Have I wore out my welcome?
I don't know if it is because this is in a word problem or what. It's got me all confused. the problem is writen as this.
The annual per capita consumption of ice cream ( in pounds) in the U.S can be approximated by a normal distribution, as shown in the graph.
The mean is 16.5 LBs, and the Distribuion is 2.5 lb.
I can't draw the graph all the way but the consumption in pounds is like this
8 10 12 14 16 18 20 22 24 26 on the graph. I need to find the smallest annual per capita consumption of ice cream that can be in the top 25% of consuptions?
and the largest annual per capita consumption of ice cream that can be in the bottom 15% of consumptions?
So would this be written like this? for A. Consumption = 25 =Area= 0.75 ->z = ? Please help with the rest...pleeze.
Could someone help me put this into a problem? Thank you in advance.
