Chapter 3: Problem 8

To discourage random guessing on a multiple-choice exam, the instructor assigns 5 points for a correct response, \(-2\) points for an incorrect answer, and 0 points for leaving the question blank. What is the score for a student who had 22 correct answers, 7 incorrect answers, and left 6 questions blank?

Short Answer

Expert verified
Answer: The student's total score on the test is 96 points.

Step by step solution

01

Calculate the points for correct answers

For 22 correct responses, the student will earn 5 points each. So, the total points for correct responses are 22 * 5 = 110.
02

Calculate the points for incorrect answers

For 7 incorrect answers, the student will lose 2 points each. So, the total points for incorrect responses are 7 * (-2) = -14.
03

Calculate the points for blank answers

For 6 blank answers, the student will earn 0 points each. So, the total points for blank answers are 6 * 0 = 0.
04

Calculate the total score

Add the points from correct responses, incorrect responses, and blank answers to find the student's total score: 110 + (-14) + 0 = 96. Therefore, the student's score is 96.
