The ratio is then 80 to 20 or
80:20.
you can also simplyfy it, by dividing both numbers by 20:
4:1
which I think is the best way to give the answer!
Let x be a random variable representing the mean number of flaws per square yard inspected
P(x > 1.8) = P(z > (1.8 - 1.7)/0.8) = P(z > 0.125) = P(z < 0.125) = 0.5497
