Once you have determined what both of your hypotheses are, you can calculate the value of your test statistic "t" based on your data set. The formula to calculate this statistic is: t = (x̄ - μ) / (s / √n) In this formula: "t" is the test statistic. "x̄" is the sample mean. "μ" is the hypothesized mean. "s" is the standard deviation of ...Then, we plug our known inputs (degrees of freedom, sample mean, standard deviation, and population mean) into the T Distribution Calculator and hit the Calculate button.
