Final Answer :
D
Explanation :
A critical value is a value that separates the regions of rejection and non-rejection on a distribution. It is determined based on the level of significance (α) and the degrees of freedom in a statistical test. It is not the same as α and is not a population parameter. The decision to reject the research hypothesis is based on comparing the test statistic to the critical value.
