Giovanna usually takes bus $B$ to work, but now she thinks that bus $A$ gets her to work faster.
She randomized $50$ workdays between a treatment group and a control group. For each day from the treatment group, she took bus $A$; and for each day from the control group, she took bus $B$. Each day she timed the length of her drive.
The results of the experiment showed that the median travel duration for bus $A$ is $8$ minutes less than the median travel duration for bus $B$. To test whether the results could be explained by random chance, she created the table below, which summarizes the results of $1000$ re-randomizations of the data (with differences between medians rounded to the nearest $2$ minutes).
**According to the simulations, what is the probability of the treatment group's median being lower than the control group's median by $8$ minutes or more?**
$\qquad$[[☃ input-number 1]]
Assume that if the probability you found is *lower* than $5\%$, then the result should be considered significant.
**What should we conclude regarding the experiment's result?**
