  1. Search and describe the main feature of the t-Distribution (or Student distribution).
Expert Solution
Step 1

The t-distribution also known as Students' t-distribution is a continuous probability distribution.

It is used to to estimate the population parameters when the population standard deviation is unknown and the sample is small.

Just like a normal distribution, student's t distribution has a bell shaped curve and the distribution is symmetrical with mean 0. This means the area to the right of the center line of the curve is same as he area to it's left.
