Observed statistic and p-value

You now have a null distribution. In order to get a p-value and weigh up the evidence against the null hypothesis, you need to calculate the difference in proportions that is observed in the late_shipments sample.

late_shipments is available; dplyr, infer, and ggplot2 are loaded.
