What do you do if none of the conditions of using a z-score or the conditions for using a t-score are met?
If we are testing a hypothesis about the population mean , if none of the conditions of using a z-score or the conditions for using a t-score are met, we may use a proper non-parametric test.
What statistic is produced when the difference between a score and the mean is divided by the standard deviation?
a "T" or a "Z" score. A "T" Score if comparing a sample. A "Z" Score when comparing a population. Remember, a population includes all observation, and a sample includes only a random selection of the population.

Mike=M Tom=T M=5+2T T+M=65 M=65-T 65-T=5+2T 65=5+3T 60=3T 20=T (Tom is 20 years old) T+M=65 20+M=65 M=45 (Mike is 45 years old)
What is the difference between z-score and t-score?
T-scores and z-scores measure the deviation from normal. The normal for T-score is 50 with standard deviation of 10. if the score on t-score is more than 50, it means that the person scored above normal (average), and vise versa. The normal for Z-score is 0. If Z-score is above 0, then it means that person scored above normal (average), and vise versa.
