With the increase in childhood obesity, the Pediatrics Association is concerned about the amount of physical activity children obtain daily. In 2012 the Pediatrics Association found that only 48% of children between the ages of five and twelve were physically active for at least one hour a day, where physically active refers to any activity that increases the child's heart rate to the aerobic zone. A random sample of 250 children between the ages of five and twelve was obtained. Of those sampled, 59% said they were physically active for at least one hour a day. At the 1% significance level, can the Pediatrics Association conclude that the proportion of children between the ages of five and twelve that are physically active for at least one hour a day has changed.
