Suppose x is the breaking strength (newtons) of a material, and x is normally distributed with
mean 800 newtons and standard deviation of 10 newtons.
a) suppose we need this material to have breaking strength of at least 772 newtons. what is the
probability that the breaking strength is at least 772 newtons.
b) what is the probability that this material has a breaking strength of at least 772 but not more
than 820?
