Question: For last example the minimum sample size is 28 (rounded). In this case our n<30. Theory says when n<30 use t-Distribution instead of z-Distribution. So, when we start determining n (using a formula with z) and we find it to be less than 30, should we re-do from start but using the formula with t? What if (if your answer is yes) now n is greater than 30 (which would imply that we should have used the z-formula)?

Hi there! I was wondering if the template used in this video was available for download or if there were instructions to create one on your channel. Thanks in advance! :)
