Answer: Therefore, the correct answer is d) 2.
Explanation:
1. Passing grade: The passing grade is defined as a score of x = 3 or higher. Any score below 3 will be considered a failing grade.
2. Distribution of quiz scores: We are given the distribution of quiz scores in the form of frequency (f) for each score (x). Let's analyze the scores:
- Score 5: f = 6
- Score 4: f = 5
- Score 3: f = 5
- Score 2: f = 3
- Score 1: f = 2
3. Count the failures: To determine the number of individuals who failed the quiz, we need to count the scores that are below 3. In this case, only the score of 2 has a value below 3.
To determine the number of individuals who failed the quiz, we need to count the number of scores that are below the passing grade of x = 3. Here's a clear and concise explanation:
4. Final answer: Since only one score, 2, is below the passing grade of 3, we can conclude that 1 individual failed the quiz.
It's important to carefully read and analyze the given distribution of quiz scores to accurately determine the number of individuals who failed the quiz.
