Conclusion
For the hour of 8 AM, the p-values in the test results show the hours of 11 PM to 9 AM being under the alpha value of 0.05, showing that 8 AM's trip duration distributions are significantly greater than those from 11 PM to 9 AM. The test results for 5 PM however show that the trip duration distribution is significantly greater than every other hour of the day. These results mean the null hypothesis can be rejected for the hour of 5 PM, and can only be rejected for 8 AM during the time span of 11 PM to 9 AM.
Weaknesses of the analysis include the incorporation of weekend days, which may not follow similar traffic pattern trends that workdays experience. Additionally, in order to focus on traffic congestion, the trip duration could be normalized by trip distance to only be comparing differences in time.
