For a one-sample t-test to achieve statistical significance, the t-obtained (the calculated t-value from the sample data) must be larger than the t-critical (the t-value from the t-distribution table that corresponds to the chosen significance level, usually .05 or .01, and the degrees of freedom for the test). This indicates that the observed data are sufficiently unlikely under the null hypothesis, suggesting that the null hypothesis can be rejected.
