A national health survey weighed a sample of 260 boys aged 6-11 and found that 45 of them were overweight. They weighed a sample of 230 girls aged 6-11 and found that 30 of them were overweight. Can you conclude that the proportion of overweight kids aged 6-11 among boys is the same as the proportion of overweight kids aged 6-11 among girls? Use level of significance 10%. Procedure: Select an answer Assumptions: (select everything that applies)
