<h3>Normal Probability Distribution</h3>The z-score of a measure X of a normally distributed variable with mean and standard deviation
is given by:
- The z-score measures how many standard deviations the measure is above or below the mean.
- Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.
The proportion more than two standard deviations below the mean is the <u>p-value of Z = -2,</u> given by 0.0228, hence 2.28% of 1-month old girls will be categorized as having microcephaly.
