Question 1075148: The weight of a certain type of chicken, when ready for the market, follows a normal distribution with mean 1.0 kg and a standard deviation of 0.20 kg. Find the probability that a chicken weighs between 0.90 kg and 1.20 kg.

z=(x-mean)/sd
This is (0.9-1)/0.2
-0.5
and (1.2-1)/0.2=1
want z between -0.5 and 1
that probability from the calculator or table is 0.5328.
