Question

For the following distribution of quiz scores, if a score of x=3 or higher is needed for a passing grade, how many individuals failed the quiz? x f 5 6 4 5 3 5 2 3 1 2 a) 5 b) 10 c) 3 d) 2

Answer 1

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.
