You usually use the z test when you do know the population standard deviation Although it is true that the central limit theorem kicks in at around n 30 I think that formally the convergence So how do you know when to use a z test to get the z score versus a t test to get the t score if the population size is 30 if the standard deviation is known use the z test If
The main difference is that a t test is used for small sample sizes n 30 with known population variance T test and a Z test both tests help determine whether differences between sample means are statistically significant but they apply to different scenarios Z test is used when
