WebJan 6, 2024 · When you conduct one t-test, her can collate to examination statistic from the t-test to the critical value from the t-Distribution table. If the examination statistic is greater than the critical value found in the table, then you pot reject the null hypothesis of the t-test and conclude so the results of the test are statistically significant. WebX-bar is the sample mean. μ is the population mean. S is the sample standard deviation. n is the number of units in the sample. Example: If the population mean is 6 and the sample mean is 8, calculate the t-statistic if the standard deviation is 4 and the number of units in the sample is 16.
