1) You are studying behavior in American Crows, specifically problem solving skills (crows are particularly intelligent).You set up an experiment where the crows must solve a puzzle for a food reward.You want to know if crows that observe other crows solving the puzzle are able to solve it faster.You select 10 crows to serve as the nave group and 10 to serve in the observer group.The nave crows (one at a time) are introduced to the puzzle and timed until they solve it (in seconds).The observer crows (one at a time) are allowed to observe their nave partner solve the puzzle and then given a chance to solve the puzzle.Since sample sizes are small you are concerned about violating parametric assumptions.
