1 The P-value is the probability of observing a sample statistic as extreme as the test statistic. 2  Since the test statistic is a t-score, use the t Distribution Calculator to assess the probability associated with the t-score, given the degrees of freedom computed above.
1 Test statistic. 2  The test statistic is a t-score (t) defined by the following equation. 3  where x is the sample mean, Î¼ is the hypothesized population mean in the null hypothesis, and SE is the standard error.he observed sample mean produced a t-score test statistic of -0.894. We use the t Distribution Calculator to find P(t. Interpret results. Since the P-value (0.19) is greater than the significance level (0.01), we cannot reject the null hypothesis.
