You are a data analyst working for a transportation magazine in Tokyo, Japan. The magazine is planning a special feature on the Tokyo metro system, highlighting the daily footfall in various metro stations. To provide readers with an accurate picture, your editor has asked you to estimate the average daily footfall.
