1. The problem asks for the range of the data set represented by the dot plot from years 1997 to 2009. 2. The range in a data set is calculated as the difference between the maximum and minimum values. 3. From the description, the highest number of dots (maximum value) is for the year 2000, which is 32 dots. 4. The lowest number of dots (minimum value) is 1 dot, which occurs in 2008. 5. Using the formula for range: $$\text{Range} = \text{Maximum value} - \text{Minimum value}$$ 6. Substitute the values: $$\text{Range} = 32 - 1$$ 7. Calculate the difference: $$\text{Range} = 31$$ 8. Therefore, the range of the data set is 31. Note: The options given (10, 11, 32, 2000) do not include 31, so the correct range based on the data is 31, which is the difference between the highest and lowest counts of dots.
