$\huge\colorbox{pink}{Answer}$

Properties of t-Distribution

• Like, standard normal distribution the shape of the student distribution is also bell-shaped and symmetrical .
• The student distribution ranges from –∞ to ∞ (infinity).
• The shape of the t-distribution changes with the change in the degrees of freedom.
• The variance is always greater than one and can be defined only when the degrees of freedom ν ≥ 3 .
• It is less peaked at the center and higher in tails, thus it assumes platykurtic shape.
