The Acme Company produces Monster Spray, a pleasant fragrance parents can use to help relax children who are afraid of nighttime monsters. A group of parents who use the spray has been recruited to find out how effective the spray is in calming monster-anxious children at bedtime. Prior to spraying, the parent will ask the child to rate his or her anxiety on a 1 to 10 scale (1 = not afraid at all, 10 = very afraid); the parent will ask the same anxiety scale question after spraying. The parent will record both the before and after (spraying) numbers.
