Quizplus · Accepted Answer

The degrees of freedom for tind is equal to the sample size minus 2, thus the correct choice is D (N - 2). This is because estimating the mean requires the use of one degree of freedom, and estimating the standard deviation requires the use of a second degree of freedom. Therefore, the total degrees of freedom for tind is N - 2.
