A factory manufactures steel poles; the length of the poles are approximately normally dis-
tributed with mean 75cm with standard deviation 1cm. Find the probability that a randomly
selected pole will be between 74.5 and 75.8cm.
Ok What i get when i try to transform this to the standard normal is
Z = .8 for X 75.8
and -.5 for X 74.5
I dont know what to do from here.
Any help greatly appreciated.
