Question

The area in the right tail more extreme than z = 3.0

Answer 1

We have to calculate P( Z > 3 ) = ?

From Z table,

P( Z > 3) = 1 - P( Z < 3)

= 1 - 0.9987

= 0.0013

Answer 2

To find the area in the right tail more extreme than z = 3.0, we need to calculate the probability that a standard normal random variable Z is greater than 3.0.

Using a standard normal distribution table or a calculator, we can find that the area to the right of z = 3.0 is approximately 0.0013.

Therefore, the area in the right tail more extreme than z = 3.0 is approximately 0.0013 or 0.13%.
