Find the z-score location of a vertical line that separates a normal distribution as described in each of the following.
- a. 5% in the tail on the left
- b. 30% in the tail on the right
- c. 65% in the body on the left
- d. 80% in the body on the right
a.
Given info: Normal distribution where z- score separates the highest 5% in the tail on left.
Calculation:
Since, Z represents the standard normal variate. Let z is the score that separates the highest 5% of the scores from the rest of the distribution...
b.
To find: The z-score that separates the 30% in the tail on right
c.
To find: The z-score that separates the 65% in the body on left.
d.
To find: The z-score that separates the 80% in the body on right.
