Nice post. I don’t know about you, but it seems that all the definitions and information regarding when to use the z-test and t-test are the same. There seems to be no discrepancy regarding this. The z-test is for sample size greater then 30 and when the standard deviation is known. Otherwise the t-test is used. I cannot find if there are any exceptions to this rule. Have you come across any exceptions to the t-test and z-test rules of when to use each hypothesis ?
