You want to find
so by standardising,
So they must make 7277 loaves
since they bake 7277 loaves, you want the probability that they sell Y less than

(a) How many loaves of bread should the compan produce?
I know i need to find n = CI * standard dev. / E .. i can figure out CI and SD. but i cant find E..
(b) Based on (a), on what percentage of days will the company be left with more than 500 loaves of unsold bread?
I'm not sure on how to do this one!
Any amount of help would be amazing!!
