It's either undergraduate students in Australia are much smarter than those
living in the United States or you live on a different planet. The last time I
taught an undergraduate introductory statistics class, some students couldn't
even do fractions and simple algebra. Can you expect them to develop their own
rules?
Why are people so obsessed with T and Z? When the degrees of freedom exceeds
say 30, the difference between T and Z is practically negligible. You can use T
or Z in such a case. However, the P-value from Z is easier to compute.
