Which of the following scenarios involving proportions would be appropriate to use the normal distribution to model the proportion?

A researcher wishes to find the probability that less than 25% of a sample of undergraduate students from Winston Salem State University will be male. He randomly samples 42 undergraduate students from the student database. The population proportion of undergraduate males at WSSU is known to be 29.3%.A researcher wishes to find the probability that more than 11% of a sample of undergraduate students from East Carolina State University will be between the ages of 25 and 34. He samples the first 105 students that walk into the gym on Monday morning. The population proportion of undergraduates between the ages of 25 and 34 is 9.9%.A grad student at UNC Asheville wants to know how likely it is that a group of students would be made up of more than 5% graduate students. She will ask 40 of her friends if they are a graduate student or an undergraduate student. The population proportion of grad students at UNC Asheville is 1.3%.A full time student at UNC Wilmington wants to know how likely it is that a group of students would be made up of more than 90% full time students. She will randomly ask 60 students their enrollment status. The population proportion of full time students at UNC Wilmington is 85%.
