*BE SURE TO SHOW YOUR WORK. 1) A psychologist is studying children's aggression in different play areas. She trains observers to rate children's aggression on a scale from 1 (low) to 10 (high), then has them observe preschool children randomly assigned to in either the art or block play areas of the classroom. She obtains the following results: Art area (n=6) x-x(x-x)² Block area (n=6) x-x (x-x)² 1-3 = -2 6-5 = 1 1 4-3 = 1 5-5 0 0 4-3 = 1 3-5 4 4-3 = 1 5-5 0 2-3 = -1 6-5 3-3 = 0 5-5 Σ = 18 Σ = 30 (X-X)² N-1 x=3.0 4 1 1 1 1 0 = (x-x) =8 = = -2 = ON = 0 1 = 0 x=5.0 1 0 =(x-x)=6
