A box plot illustrates the distribution of scores on a standardized aptitude test for a group of job applicants. The plot shows the minimum score at 60, the first quartile (Q1) at 75, the median at 85, the third quartile (Q3) at 92, and the maximum score at 100. Which of the following statements can be inferred from this box plot?

A Exactly 25% of applicants scored 75.
B More applicants scored above 92 than below 75.
C The middle 50% of applicants scored between 75 and 92.
D The average score is exactly 85.

✓ Correct Answer: Option C

The box in a box plot represents the interquartile range (IQR), which spans from Q1 to Q3. Therefore, the middle 50% of data points fall between the first quartile (75) and the third quartile (92).
