Now that you are an adult, you decide to test one of the truisms passed along by your mother: "Cheaters never win in the end." You have a group of children participate in the scavenger hunt without cheating and record the numbers of items found by each child. Then you have the same group of children participate in a scavenger hunt with instructions to cheat, and you measure the number of items found by each child. What statistical test would you use to compare the number of items found by each child when cheating versus not cheating?

a. paired-samples t test

b. z test

c. independent-samples t test

d. single-sample t test
