which of the following does not need to be known in order to compute the t-critical value? group of answer choices knowledge of whether the test is one-tailed or two-tailed. the level of significance. degrees of freedom. the value of the test statistic.



Answer :

Answer:

the value of the test statistic.

The t-critical value is used to determine whether the results of a statistical test are statistically significant. In order to calculate the t-critical value, the following information is needed: the level of significance (often denoted as alpha or p-value), the degrees of freedom, the sample size, and whether the test is one-tailed or two-tailed. The value of the test statistic is not needed to compute the t-critical value. The t-critical value is based on the level of significance, the degrees of freedom, and the sample size, and it is used to compare the test statistic to determine whether the results are statistically significant.
