The Z-test is used to determine if there is a significant difference between the means of two groups or to assess whether a sample mean significantly differs from a known population mean. It is applicable when the population variance is known, and the sample size is large (typically n > 30), allowing for the assumption of normality. The Z-test helps in hypothesis testing by calculating the Z-score, which indicates how many standard deviations a data point is from the mean.
