Parents who condone spanking. In Exercise 4.188 (p. 241) you read about a nationwide survey that claimed that 60% of parents with young children condone spanking their child as a regular form of punishment (Tampa Tribune, Oct. 5, 2000). In a random sample of 100 parents with young children, how many parents would need to say that they condone spanking as a form of punishment in order to refute the claim?
