13. The next question refers to the graph below. How many persons had blood counts between 4 and 6 million/mm3 inclusive?
Answer: C
75 persons had blood counts between 4 and 6 million/mm3 inclusive.
The data indicates that the number of persons with blood counts within the specified range is 75.
A) 200
This option is incorrect as it overestimates the number of persons with blood counts between 4 and 6 million/mm3. The graph clearly shows a much lower count within this range.
B) 130
This option is also incorrect. Although it is closer than option A, the actual count for blood levels between 4 and 6 million/mm3 is lower than 130, as evidenced by the data presented in the graph.
C) 75
This is the correct answer, reflecting the accurate count of individuals who had blood counts between 4 and 6 million/mm3. The graph clearly indicates that this is the number of persons within the specified range.
D) 205
This option is incorrect as it significantly exceeds the actual number of persons with blood counts between 4 and 6 million/mm3. The graph does not support a count this high for the specified range.
Conclusion
The correct answer is 75, as it directly matches the findings depicted in the graph regarding blood counts between 4 and 6 million/mm3. All other options are incorrect as they either overestimate or misrepresent the actual data shown, demonstrating a clear understanding of the information provided.
