Methodology
Originally, Mann Whitney U test, Chi-square test, and Fisher's Exact test were selected for test performing. After comparing with testing for New York City's Prison Employment Program Effectiveness (Bianco, 2018), Chi-squared test was selected as the primary option. For Chi-square test, the two variables are independent, which in this project, subscribers are independent of customers. Particularly in this project, Chi-square test for equality of proportions is used (Boslaugh & Watters, 2008). Therefore, three methods were considered but Chi-square was determined as the best choice. 5000 random samples were drawn from each category (weekday rides and weekend rides; process shown below). The processes and testing results of Mann-Whitney U test and Fisher's Exact test can be found in the Appendix section.
