Explanation:

Step1: Recall relative frequency formula

Relative frequency is calculated as the absolute frequency of a class divided by the total number of observations. The formula is \( \text{Relative Frequency} = \frac{\text{Absolute Frequency of the Class}}{\text{Total Number of Observations}} \).

Step2: Identify the relevant values

For the ticket prices between $200 - $249, the absolute frequency (from the frequency distribution table) is 7. The total number of observations (total absolute frequency) is 100 (from the TOTALS row).

Step3: Calculate the relative frequency

Using the formula, we substitute the values: \( \text{Relative Frequency} = \frac{7}{100} = 0.07 \) or 7%.

Answer:

7% (corresponding to option c)
