Which of the following is true for a given level of confidence?
A) As sample size increases, the value of the critical t-ratio decreases.
B) As degrees of freedom increase, the value of the critical t-ratio decreases.
C) Both A and B are correct.
D) Neither A nor B is correct.

Both statements A and B are correct because as the sample size increases, the degrees of freedom (which is sample size minus one for a single sample t-test) also increase. This leads to a decrease in the value of the critical t-ratio, making the t-distribution approach the normal distribution as the sample size grows.
