T-Statistic Degrees of Freedom and Significance
In a t-test for a population mean, how do the calculated t-statistic and the degrees of freedom jointly influence the interpretation of the test’s significance?
A
A smaller absolute t-score relative to the critical value (determined by degrees of freedom) indicates stronger evidence against the null hypothesis.
B
A larger absolute t-score relative to the critical value (determined by degrees of freedom) indicates stronger evidence against the null hypothesis.
C
The degrees of freedom always determine the t-score, regardless of the sample statistics.
D
The relationship between t-score and degrees of freedom is irrelevant in determining the test’s significance.
