The z score is a score used in statistics to determine by how many standard deviations the raw score is above or below the mean. The z score is given by:

For a normal distribution with a mean of μ and standard deviation σ, For any sample size (n) drawn from this population, the sample mean is normally distributed, with mean
and standard deviation
.
Hence given that a mean of μ = 20.6 years and standard deviation σ = 5.3 years, for a sample size of 100:
mean
and standard deviation
