If the sample size (\( n \)) is 32 in testing of hypothesis by t-test, then the degree of freedom (\( \nu \)) is equal to :
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → 31
In a t-test on a single sample of size n, the degrees of freedom are \( \nu=n-1 \):
\( \displaystyle \nu=32-1=31 \)
