Porter offers flights to and from the Island airport in Toronto, providing faster access to the downtown area than Pearson International Airport, which is farther from the city centre. Porter’s fare structure focuses on business passengers; it also provides complimentary refreshments and internet access in its Toronto and Ottawa airport lounges. As a new member of Porter’s Marketing Department, you want to boost the number of student passengers on the Ottawa–Toronto route. Suppose you examine last year’s sample of passengers and find that 6% of them were students. Of those, 92% used the free internet service, as opposed to only 61% of the other passengers.
QUESTION: 

What kind of study is this? Can you conclude that internet use is a factor in deciding to fly with Porter?
