Verified step by step guidance

1. Identify the total number of questions on the test, which is 20, and the number of questions answered correctly, which is 16.
2. Understand that the mean score per question is calculated by dividing the number of correct answers by the total number of questions.
3. Set up the fraction representing the mean score per question as \(\frac{16}{20}\), where 16 is the numerator (correct answers) and 20 is the denominator (total questions).
4. Simplify the fraction if possible to express the mean score in its simplest form.
5. Interpret the result as the average score per question, which can also be converted to a decimal or percentage if needed.
