control. (a) True (b) False 13. Students take a 100-point true/false exam. Assume the test is scored such that a student receives one point for a correct answer and loses a point for an incorrect answer. For example, assume a student knew 90 of the answers and guessed correctly on 7 of the remaining 10 (and therefore incorrectly on 3). Their true score would be 90 since that is the number of answers they knew. Their actual test score would be 90+4. What's their error score? (a) 7 (b) 3 (c) 4 (d) 0 14.
