A cognitive psychologist working in the area of suggestion asked a sample of children to solve as many problems as they could in 20 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 hypothesizes that thinking it is a time- filling task will improve problem solving. What can be concluded with a = 0.05? Below is the data for the number of problems solved.
