In order to determine the critical value, which two pieces of information are needed?
A) mean and sample size
B) degrees of freedom and level of significance
C) mean and standard deviation
D) degrees of freedom and variance

Question

Quizplus · Accepted Answer

Critical values are based on the level of significance and degrees of freedom. These values are used to determine if the test statistic falls in the critical region, which would lead to rejection of the null hypothesis. The mean, standard deviation, and variance are all used to calculate the test statistic, but they do not determine the critical value.
