Looking at ______ for a statistic like a t-statistic provides an indication of the directionality of the alternative hypothesis.
A) the null hypothesis
B) alpha
C) the critical values
D) the sample size
Critical Values
Thresholds in statistical hypothesis testing that determine the cutoff points for rejecting or not rejecting the null hypothesis.
T-statistic
A type of statistic used in hypothesis testing, calculated by dividing the departure of an estimated parameter from its hypothesized value by its standard error.
Sample Size
The number of observations or data points that constitute a sample in a statistical study.

Final Answer :
C
Explanation :
The critical values in statistical tests, including those involving a t-statistic, help determine the directionality of the alternative hypothesis by indicating the threshold beyond which the null hypothesis is rejected. This can show whether the test is one-tailed (directional) or two-tailed (non-directional).
