Answer 2

Given :

Student's t- distribution has (n-1) d.f.

Answer :

minimum

Step-by-step explanation:

The simple answer is that df = n- 1 in the t distribution, where n is the number of cases in an independent two sample test or a one sample test or the number of dyads in a paired test.

And, as df goes up, the t distribution gets near to a normal. At df = 30 or so, the two are nearly indistinguishable.

The more complex answer is that df relates to how numerous effects can vary. However, the last observation is determined, If you know the mean and n- 1 compliances.
