Math Problem Statement
Solution
The image you uploaded shows a request to find the z-score that corresponds to the 82nd percentile (P82) using the standard normal table.
To find the z-score for P82:
- Look up the closest area (probability) of 0.8200 in the z-table.
- Find the corresponding z-score for this area.
Based on the standard normal distribution table, the z-score corresponding to the cumulative area of 0.8200 is approximately 0.92.
So, the z-score corresponding to P82 is 0.92.
