Two people produce apples. The first one with
a diameter normally distributed with an average of 3 cm and standard deviation
of 0.1 cm.
The second one with a diameter which is normally distributed with an average of 3.04 cm
and standard deviation 0.02 cm.
We only need a diameter between 2.9 cm and 3.1 cm. We randomly take an apple.
Now it appears that this apple is too big and is therefore not accepted. What is the chance that the apple
was made by the first device?
My answer: 99 %
Is my answer correct?
