To determine which event had a higher median number of visitors, we would need to analyze the box plots provided for the live dolphin show and the movie about dolphins in the wild.
The median in a box plot is represented by the line inside the box. If the line for the live show is positioned higher than the line for the movie, then the live show had a higher median number of visitors, and vice versa.
Since I cannot see the box plots, I recommend you look for the line within each box to find the median for both events and compare them. Please let me know the values if you need further help!
