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
