Question

For the z-scores below, find the percentile rank (percent of individuals scoring below): a. -0.47 b. 24?

Answer 1

To find the percentile rank for a given z-score, you can use the z-table.

Step-by-step explanation:

The percentile rank can be found using the z-table. For a z-score of -0.47, we can look up the area to the left of -0.47 in the z-table, which is approximately 0.3186. This means that about 31.86% of individuals score below -0.47.

For a z-score of 24, we can look up the area to the left of 24 in the z-table, which is approximately 1.0000. However, the z-table only provides values up to 3.09, so for a z-score of 24, we can say that approximately 100% of individuals score below 24.
