The process of determining a t-value for a certain confidence level requires utilization of a t-distribution table. This method is predominantly employed in the execution of hypothesis testing and the formation of confidence intervals, particularly when dealing with a small sample size or when the population standard deviation is not known. The t-value is contingent on both the size of the sample and the chosen confidence level.
