Okay, so this
may seem a bit simple for here, and I wasn't sure, but this is from my University past paper. The question reads:
A chocolate company produce boxes of chocolates with mean . It is decided that all boxes weighing less than or more than will be re-packed. If the weight of the boxes is Normally distributed with standard deviation , what percentage of boxes will be repacked?
So I got from this that...
and I was trying to find
(because the stuff in the
would be the boxes that were the right weight, so 1 minus that would be boxes to be repacked). However, after standardising and using the tables I'm given and what not, with this I get a percentage that, to me, seems a bit high
something like 43%.
Can anyone help? Have I made a misunderstanding somewhere?
