The frequency polygon to the right shows a distribution of IQ scores. Determine if the following statement is true or false according to the graph. The graph is based on a sample of approximately 50 people. Choose the correct answer below. *** Number of People (frequency) 30 20 10 5 70 Distribution of IQ Scores 80 90 O A. The statement is true because the sum of the frequencies is 50, OB. The statement is false because the sum of the frequencies is greater than 50. O C. The statement is true because there are 50 possible IQ scores. OD. The statement is false because there are less than 50 possible IQ scores. 100 110 120 130 IQ Score

Question
The frequency polygon to the right shows a distribution of IQ scores. Determine if the following statement is true or false according to the graph.

The graph is based on a sample of approximately 50 people.

**Graph Explanation:**
The graph titled "Distribution of IQ Scores" displays the number of people on the y-axis (frequency) against IQ scores on the x-axis, ranging from 70 to 130. The graph shows a symmetric distribution with a peak around the IQ score of 100, indicating the mode of the distribution.

**Choose the correct answer below:**

- **A.** The statement is true because the sum of the frequencies is 50.
- **B.** The statement is false because the sum of the frequencies is greater than 50.
- **C.** The statement is true because there are 50 possible IQ scores.
- **D.** The statement is false because there are less than 50 possible IQ scores.
