Here is a really neat applet that will take the place of your z-score tables

http://davidmlane.com/hyperstat/z_table.html

You can experiment with both graphs.

Since you want .5% of the bags to be underweight, you are looking for an

"area" of .495 (I took .5 - .005)

On the second graph, enter 0.495 in the area

and 10.4 and .26 into the mean and sd boxes.

click on "below"

Change the mean and sd entries and see what happens.
