At some vacation destinations, "all-inclusive" resorts allow you to pay a flat rate and then eat and drink as much as you want. There has been concern about whether these deals might lead to excessive consumption of alcohol by young adults on spring break trips. You decide to spend your spring break collecting data on this issue. You collect data on the number of drinks consumed in a day by people staying at all-inclusive resorts and by those staying at non-inclusive resorts. You data include the following:
All-inclusive resort guests:
10, 8, 13
Non-inclusive resort guests: 3, 15, 7
