I wanted to investigate whether or not there was a relationship between a Citibike rider's age and trip duration. I hypothesized that younger riders would take longer Citibike trips--perhaps because they are more comfortable riding a bicycle over longer distances in New York City. I categorized a subset of my Citibike trips into "Young" (aged 18 - 35) and "Old" (aged 43-60) in order to determine if there was a statistically significant difference in mean trip duration. I employ an unpaired t-test which yielded a t statistic of 29.448 with a p-value of 0.00. This indicates a statistically significant difference in sample means between old and young riders.
