The standard normal curve can be used as a model for any approximately normal distribution when transformed to z-scores. This is because the process of standardizing a distribution by transforming it into z-scores converts any distribution into a standard normal distribution with a mean of 0 and a standard deviation of 1. Therefore, using the standard normal curve can help us make statistical inferences and calculations based on the properties of the standard normal distribution, regardless of the specific shape of the original distribution.
