"WebTo find the percentile of a specific value in a normal distribution, find the z-score first by using the formula. Z= (x-μ)/σ where μ is the mean and σ is the standard deviation of the data set. Then look up that z-score on a z-score table. The corresponding number in the z-score table is the percentage of data below your value. " - Normal curve with percentages
