If a counseling psychologist wants to know if doubling the number of counseling sessions attended by students experiencing severe test anxiety will reduce or increase the amount of anxiety the students report just before a test, the statistical test the psychologist would use would be
A) one-tailed because only one issue is discussedtherapy sessions.
B) two-tailed because there are two variableswhether or not students undergo therapy and how anxiety is affected.
C) two-tailed because the direction of the effect of increasing the amount of therapy is not predicted.
D) one-tailed because there is only one interaction between the therapy and anxiety.
