In which of the following scenarios do the critical values of a z-test and t-test differ the least?

Question

A) 10

B) 92

C) 58

D) 50

Answer 1

There are no scenarios there! The number 10 is not a scenario in and of itself, but it is important to understand that the student's t function becomes approximately normal as the degrees of freedom get large. The larger the degrees of freedom you have in evaluating a t, the closer you get to having the same score on a normal curve.
