Webt-Tests Use t-Values and t-Distributions to Calculate Probabilities Hypothesis tests work by taking the observed test statistic from a sample and using the sampling distribution to calculate the probability of obtaining that test statistic if the null hypothesis is correct. WebHere is formula that is in books and in Internet for calculating t-score: t = X ¯ − μ S n As far as I know μ is used to define true population mean. So in formula above I need true population mean μ to calculate t-score. But as I said before when calculating t-score we don't know true population parameters, in this case true population mean μ.
