In a survey of 9300 twelfth grade males, 2083 said they had smoked in the last 30 days. In a survey of 4900 twelfth grade females, 985 said they had smoked in the last 30 days. At a=0.01, can you support the claim that the proportion of twelfth grade males who said they had smoked in the last 30 days is less than the proportion of twelfth grade females who said they had smoked in the last 30 days?
