What is the alternative hypothesis when testing if wait times are longer on weekends than weekdays?

The alternative hypothesis is a statement that indicates a difference or effect exists in the population being studied. In this case, when investigating whether wait times are longer on weekends compared to weekdays, the alternative hypothesis specifically posits that there is a difference in the average wait times between these two timeframes.

Choosing the statement that asserts the average wait time is longer on weekends accurately reflects the research question being addressed. It directly supports the idea that weekends impact wait times differently than weekdays, which is the focus of the investigation.

The other options do not accurately represent the alternative hypothesis for this scenario. One option suggests that wait times are shorter on weekends, which contradicts the hypothesis under investigation. Another states that the average wait time is the same for both periods, representing a null hypothesis rather than the alternative. Lastly, one option implies that wait times are longer on weekdays, which is contrary to the claim being tested regarding weekend wait times. Therefore, the chosen statement stands out as it aligns perfectly with the goal of demonstrating that weekends are associated with longer wait times.
