You could try carrying out some form of hypothesis testing.
Null Hypothesis: Mean sales of the standard product in a day is mu Alternate Hypothesis: Mean sales of the standard product in a day in mu
- Null Hypothesis: Mean sales of the standard product in a day $ = \mu$.
- Alternate Hypothesis: Mean sales of the standard product in a day $ \neq \mu$
You could then extract the rows where ride type is standard and split it into 2 time periods - before and after the premium services were introduced. You could then aggregate your sales by days or weeks (your choice on the time frame) and then carry out a Z/T-test using the above hypothesis with a chosen significance level.
