Problem 1
An investigator is interested in knowing whether managers who were raised under authoritarian child-rearing practices are more authoritarian in their management practices than those raised in more democratic home backgrounds. He gets 300 managers to complete questionnaires that indicate the sort of child-rearing practices they experienced. From the results, it was possible to divide the 300 managers into 170 who came from democratic homes and 130 from authoritarian homes. The management practices of these two groups were assessed using rating scales completed by their subordinates.
