A scatter plot shows 'Hours Studied' on the x-axis and 'Exam Score' on the y-axis for 15 students. The plot generally shows an upward trend, indicating that more hours studied correlate with higher exam scores. However, one student studied 10 hours and scored 60, while another studied 5 hours and scored 90. Which of the following statements about these two students is most likely true?

A The student who studied 10 hours is an outlier, scoring significantly lower than expected for their effort.
B The student who studied 5 hours is an outlier, scoring significantly higher than expected for their effort.
C Both students demonstrate a typical performance pattern for their respective study hours.
D The data suggests that studying more hours always leads to a lower score for some students.

✓ Correct Answer: Option B

Given an upward trend, 5 hours of study yielding a 90 score is unusually high, making that student an outlier. A 10-hour study with a 60 score is unusually low, but the question asks 'most likely true' in context of the 'upward trend' implying higher scores with more study.
