Step 1: Understanding the Concept:
This is a data interpretation problem involving pie charts for two different states (State A and State B).
To evaluate the statements, we must calculate the absolute values of the specified categories using the given percentages and the total populations of each state.
Key Formula or Approach:
- Total Population of State A, \(N_A = 55750\)
- Total Population of State B, \(N_B = 86500\)
- Number of people in a category = \((\text{Percentage of Category}) \times \text{Total Population}\)
Step 2: Detailed Explanation:
Let us calculate the values for each statement systematically:
- Evaluating Statement I:
- Percentage of Undergraduates in State A = \(28\%\)
\[ \text{Undergraduates in State A} = 55750 \times 0.28 = 15610 \]
- Percentage of Undergraduates in State B = \(40\%\)
\[ \text{Undergraduates in State B} = 86500 \times 0.40 = 34600 \]
- Total Undergraduates = \(15610 + 34600 = 50210\).
Therefore, Statement I is true.
- Evaluating Statement II:
- Percentage of Ph.D in State A = \(8\%\)
\[ \text{Ph.D in State A} = 55750 \times 0.08 = 4460 \]
- Percentage of Ph.D in State B = \(10\%\)
\[ \text{Ph.D in State B} = 86500 \times 0.10 = 8650 \]
- Ratio of Ph.D students in State A to State B:
\[ \text{Ratio} = \frac{4460}{8650} \approx 0.515 \]
Therefore, Statement II is false.
- Evaluating Statement III:
- Difference in Ph.D students between State B and State A:
\[ \text{Difference} = 8650 - 4460 = 4190 \]
Therefore, Statement III is false.
Thus, only Statement I is true.
Step 3: Final Answer:
The correct option is (D) Only Statement (I) is true.
