A study revealed that among 2428 boys aged 7 to 12 years, 461 were overweight or obese. On the basis of this study, can we conclude that more than 15 percent of the boys aged 7 to 12 years in the sampled population are obese or overweight? Let α = 0.01

In an article in the journal Health and Place, Hui and Bell found that among 2428 boys ages 7 to 12 years, 461 were overweight or obese. On the basis of this study, can we conclude that more than 15 percent of the boys ages 7 to 12 in the sampled population are obese or overweight? Let alpha=0.05. Conduct a hypothesis test by hand.

In a study conducted by the U.S. Department of Health and Human Services, a sample of 546 boys aged 6-11 was weighed, and it was determined that 87 of them were overweight. A sample of 508 girls aged 6-11 was also weighed, and 74 of them were overweight. Can you conclude that the proportion of boys who are overweight differs from the proportion of girls who are overweight?
