  1. I
    The t-distribution is a symmetric distribution about the mean zero (like the z-distribution)
  2. II
    the t-distribution is a continuous distribution
  3. III
    the t-distribution has broader tails, that is, more area or probability towards the ends than a z-distribution.
  4. IV
    If the sample size n approaches ∞ then the t-distribution approaches the z-distribution
  5. V
    If the sample size is n, then t has an n-1 degree of freedom. The shape of the t-distrubution curve depends upon the degree of freedom (the higher the d.f. the closer to z-distribution)
