When to use the z-table or t-table
Please may you clarify when you should use the z-table and the t-table?
I just sat the practise exam and got the wrong figures for question 3) as I was using the t-table when I was supposed to using the z-table
(I seem to remember that for sample data smaller than n = 50, [n<50] you should use the t-table )

Page number 25 acts like a cheat sheet that tells you which one to use in which cases.
