Question: A study of 770 adults in the US showed that 4.3% were victims of specific phobias badly enough to prevent functioning normally. A survey of 790 adults in Australia showed that 2.9% were victims of specific phobias badly enough to prevent functioning normally. Does the data indicate the population proportion of US adults who are victims of specific phobias is greater than the population proportion of Australians who are victims of specific phobias?
