Question

Quizplus · Accepted Answer

The t distribution has broader tails than the z distribution, meaning that it has more probability in the tails of the distribution compared to the z distribution. This is because the t distribution takes into account the uncertainty in the estimation of the population standard deviation, which leads to more variability in the distribution. As the sample size increases, the t distribution becomes closer to the z distribution.
