Usage of different tests!

Question

Hello, team! So if our sample size is greater than 30, we use z-test? or t-test? Regards,

Answer 1

Hi Anantee,

You can use either.

Just keep in mind that when n>30, t-score and z-score will coincide.

Therefore we say: 'for simplicity, you can just use z-test'.
