Identify the following as an experiment or an observational study.
-A newspaper holds a contest and asks readers to send in their answers to a set of questions. 105 people answer
all questions correctly. Of these, 10 will be selected at random to win a trip to Hawaii. The 105 people are listed
in alphabetical order. An assistant starts with the first name and rolls a fair die. If the die comes up 6, that
person will be selected. If it doesn't come up 6, the assistant moves on to the next person. Once 10 people have
been selected, the assistant stops.
