1. The problem asks for the interquartile range (IQR) of the number of customers Mr. Rubio served on weekends, based on the box plot data. 2. The interquartile range is calculated as the difference between the third quartile (Q3) and the first quartile (Q1): $$\text{IQR} = Q3 - Q1$$ 3. From the box plot, we identify: - First quartile (Q1) $\approx 22$ - Third quartile (Q3) $\approx 29$ 4. Substitute these values into the formula: $$\text{IQR} = 29 - 22$$ 5. Calculate the difference: $$\text{IQR} = 7$$ 6. Therefore, the interquartile range of the weekend customers is 7.
