1. The Lucky Pen Peter noticed that every time he used his special pen with green ink, something wonderful would
happen to him. First, he got an A on his history exam. When he loaned his pen to Amy, she later
agreed to go out on a date with him. While he was carrying his pen, he bought a lottery ticket
that later won $2,000. He decided that his pen truly had lucky powers and he put it away so he
wouldn't lose it.
Would this conclusion be derived from a correlational study or an experiment? Why?
