What statement is accurate about decision theory in understanding the statistical analysis process?
A) The level of significance falls within a range based on the degrees of significance.
B) It assumes that the groups in a study used to test a hypothesis are components of different populations relative to the variables under study.
C) It is used to explain the extent of a relationship,the probability that an event will occur in each situation,or that an event can be accurately predicted.
D) It requires that the cutoff point selected for a study be absolute.

Decision theory requires that the cutoff point selected for a study be absolute.Absolute means that even if the value obtained is only a fraction above the cutoff point,the samples are considered to be from the same population,and no meaning can be attributed to the difference.The level of significance is dichotomous,meaning that the difference is significant or not significant; there are no "degrees" of significance.Decision theory also assumes that all of the groups in a study used to test a particular hypothesis are components of the same population relative to the variables under study.Probability theory is used to explain the extent of a relationship,the probability that an event will occur in a given situation,or that an event can be accurately predicted.
