Question

Z score can never be greater than 10 (T/F)

Answer 1

Solution:
This statement is false that Z-score can never be greater than 10.
Normal Distribution area can be written as
P(-∞<=Z<=∞) = 1
If we distribute area in normal distribution curve than we will get
P(-∞<=Z<=0) = 0.5
P(0<=Z<=∞) = 0.5
So This statement is false that Z -score can never be greater than 10 and Z score can take any value from -∞ to ∞.
