To examine the effect of instructions on the time required to solve a puzzle, 90 subjects were randomly assigned to one of three groups. While providing instruction, one group was told that their task was easy, another group was told that their task was hard, while the final group was given no instruction at all. The dependent variable was the time, in minutes, required by each subject to solve the puzzle.

1. What experimental design is used in this study?

2. What is the appropriate statistical test for testing whether the method of instruction had an effect on the time it took for subjects to complete the puzzle? Explain how you reached your choosing of statistical test.
