A dietitian read in a survey that 55% of children eat breakfast before going to school. The dietitian believes that the proportion is much higher. To verify her claim, she selected a random sample of 80 children and asked them if they eat breakfast in the morning. 52 of the children said they eat breakfast before going to school. At α = 0.05, is the claim realistic? This is a right-tail test.
