P-Value will be –. P-Value = P (z ≥ 2.09) We have to look at the value of 2.09 in the Z table. So, we have to look at -2.0 in the z column and the value in the 0.09 column. Since the normal distribution is symmetrical, the area to the right of the curve is equal to that on the left. So, we get the P-Value as 0.0183.
