The figure below shows two overlapping probability distributions: The left distribution (I) corresponds to impostor attempts, the right distribution (A) corresponds to authentic users, and a decision threshold is used to decide whether to accept or reject a person. Four possible outcomes exist depending on which side of the threshold the sample falls (A-D each letter is marked in a distinct region of the figure). Match each outcome below with the correct region: False Positive (Type II Error) (5 points) Correct Rejection (True Negative) (5 points) False Negative (Type I Error) (5 points) Correct Acceptance (True Positive) (5 points)
