James drives his car to his job using an identical route each day. He noticed that the time it takes him to get to work (“commute time”) is sometimes impacted by the time at which he leaves his house. For 50 consecutive trips to his job, James noted how long his commute time took (in minutes), as well as whether he left his house before or after 8:00AM. The histograms below show the distribution of commute times on the 24 days he left his house after 8:00AM as well as on the 26 days he left his house before 8:00AM.
a. Write a few sentences comparing the distribution of commute times for days when James leaves his house before 8:00AM vs the days when James leaves his house after 8:00AM.
b. Based on the histograms, which set of days has a larger mean commute time? Justify your response.
