Abstract

The purpose of this project is to see whether the average trip duration of Citi bike subscribers was significantly larger than the average trip duration of one time customers, in accordance with our hypothesis. I  set my null hypothesis as the average trip duration of subscribers biking are equal to the average trip duration of non-subscribers.  And I chose alpha equals to 0.05 as my significance level. After data cleaning, I apply Mann-Whitney U test to test my null hypothesis since my sample data is not normally distributed. The test result shows that p-value is nearly zero, indicating that there is statistical significance evidence to reject the null hypothesis. So the average trip duration of Citi bike subscribers was significantly different from the average trip duration of one time customers with a significance level of 0.05.
