1. According to the table, what is the relative frequency of Students ages 14-17 who skip breakfast?

Correct Answer: Correct answer is: (A) About 27%.

Exam Relevance: SAT, ACT, GRE, GMAT

Difficulty: Moderate

Concept notes: Relative frequency is calculated by dividing the number of occurrences of a specific event by the total number of observations.

Common Mistakes: A common mistake is to confuse relative frequency with absolute frequency, which is the raw count of occurrences without normalization.

Explanations: To find the relative frequency of Students ages 14-17 who skip breakfast, we need to divide the number of Students ages 14-17 who skip breakfast by the total number of Students ages 14-17. According to the table, the number of Students ages 14-17 who skip breakfast is 270, and the total number of Students ages 14-17 is 1000. Therefore, the relative frequency is calculated as follows: \[ \text{Relative frequency} = \frac{270}{1000} = 0.27 \] This is equivalent to 27%.

Option Analysis:

Option A: Correct. The relative frequency is 27%.
Option B: Incorrect. 35% is not the correct relative frequency.
Option C: Incorrect. 15% is not the correct relative frequency.
Option D: Incorrect. 30% is not the correct relative frequency.
