in a standard normal distribution, which z - score represents the 20th percentile? find the z - table here. -1.41 -0.84 0.84 1.41

Answer

Answer:

B. -0.84

Explanation:

Step1: Understand z - table usage

The z - table gives the cumulative probability from the left - hand side of the standard normal distribution.

Step2: Locate 20th percentile

We want to find the z - score for which the cumulative probability is 0.20. Looking up 0.20 in the body of the standard normal z - table (the area under the curve to the left of the z - score), we find that the closest value corresponds to a z - score of approximately - 0.84.
