Question
Given that is a standard normal random variable, find for each situation (to 2 decimals).
The area between -z and z is 0.9050 .
The area to the left of z is 0.9953 .
The area to the right of z is 0.6950 . (Enter negative value as negative number.)
Expert Solution
Step 1
Given that Z is a standard normal random variable,
We have to find the value of Z
Where the areas are given below
The area between -z and z is 0.9050 .
The area to the left of z is 0.9953 .
The area to the right of z is 0.6950 .
By using formula
Z score = (x-meu)/sigma.
