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. Webt = X ¯ − μ S n. As far as I know μ is used to define true population mean. So in formula …
