Hi everyone... as you can tell I'm completely new to this forum. I'm studying A-level math in the UK and although I find it considerably more chalenging than my other subjects I do enjoy it. Hopefully I'll be able to give something back to this forum as I learn.
This is the question I'm stuck on:
Jam is packed in tins of nominal weight 1000g. The actual weight of Jam delivered to a tin by the filling machine is normally distributed about the mean weight set on the machine with a standard deviation of 12g. The average filling of Jam is 1000g.
It is a legal requirement that no more than 1% of tins contain less than the nominal weight. b) Calculate the minimum setting of the filling machine which will meet this requirement.
The answer in the back of the textbook is 1028g
The book doesn't not provide a worked solution, and even though I think the working is pretty straightforward, I have no idea where to start. Any help would be greatly appreciated
