Childhood obesity: A national health survey weighed a sample of 532 boys aged 6-11 and found that 73 of them were overweight. They weighed a sample of 468 girls aged 6-11 and found that 65 of them were overweight. Can you conclude that the proportion of boys who are overweight is less than the proportion of girls who are overweight? Let p denote the proportion of boys who are overweight and let p2 denote the proportion of girls who are overweight. Use the α = 0.05 level of significance and the P-value method with the TI-84 Plus calculator.
