Question

If you randomly selected someone from a normal population, what is the probability, to the nearest whole percent that his or her z-score would be above -1.8

Answer 1

- use a z-table, or a z-score to percentile calculator, to convert the z-score to the appropriate percentile
- as a reminder, the percentile is the % of values that are *below* the given value. so to find the % of values *above* the value, take your value from the previous step, and subtract it from 1
