How do you make a decision to z test? - Answers

To decide whether to use a z-test, first determine if your sample size is large (typically n > 30) and if the population standard deviation is known. Ensure that the data is approximately normally distributed or follows a normal distribution. If these conditions are met, you can proceed with a z-test to compare sample means or proportions against a known population parameter.
