The numerator of the z-score test statistic measures the actual distance between the sample mean (M) and the population mean (µ) in terms of standard errors. It is calculated by subtracting µ from M and dividing the result by the standard error of the mean (SEM). This value is then compared to the critical z-value to determine if the difference between M and µ is statistically significant.
