An applicant's performance rating consists of three criteria: Written Exam (85, weighted 30%), Interview (90, weighted 40%), and Credentials (75, weighted 30%). What is the composite rating?
Answer and explanation
Correct answer: D. 84.0
- Step 1: Written Exam: 85 0.30 = 25.5. Step 2. Interview: 90 0.40 = 36.0. Step 3. Credentials: 75 0.30 = 22.5. Step 4. Composite rating = 25.5 + 36.0 + 22.5 = 84.0. Answer: 84.0, calculating 85(0.30) + 90(0.40) + 75(0.30) = 25.5 + 36.0 + 22.5. Why not the others:* 83.33 is the unweighted average (85 + 90 + 75)/3.
