A developmental psychologist working in the area of suggestion asked a sample of children to solve as many problems as they could in 15 minutes. Half of the children are told that this is a problem-solving task and the other half are told that this is just a time-filling task. The psychologist is interested in the impact of the suggestion on problem solving. What can be concluded with an α of 0.01? Below is the data for the number of problems solved.
A) Condition 1 = Condition 2=
