As per the central limit theorem, when the sample size (N) is larger than or equal to 30, the distribution of the sample mean becomes normal regardless of the shape of the population from which it is drawn. Therefore, when N > 40 and the raw scores in the population are normally distributed, the normal and t distributions are quite similar to each other.
