A government department in Aridzona plans to run an advertising campaign suggesting various ways that people could reduce their water usage. One of the suggested proposals is to limit showers to less than 3 minutes, but a detractor of the scheme claims that on average people are already spending less than 3 minutes in the shower. Suppose a researcher asked 100 people living in Aridzona to record the amount of time they spent in the shower on the following day.

What analysis would be required to test if the average length of shower in Aridzona is less than 3 minutes?
