If a sample has 45 people in it, the degrees of freedom used in the formula to estimate the population variance would be: A)45² B)45/2 C)44 D) .22

Question

Quizplus · Accepted Answer

The degrees of freedom used in the formula to estimate the population variance is n-1, where n is the sample size. Therefore, in this case, the degrees of freedom would be 45-1, which equals 44. Option A is not a valid answer as it does not relate to the question. Option B is incorrect as it assumes a specific scenario that is not stated in the question. Option D is incorrect as it is not a whole number that could represent degrees of freedom.
