As the sample size increases, the degrees of freedom for a t-distribution also increase, causing the shape of the distribution to more closely resemble a normal distribution. This is because the t-distribution accounts for the additional uncertainty in estimating the population standard deviation from a sample, and as sample size increases, this estimate becomes more accurate, making the t-distribution look more like the normal distribution.
