A school district claims that the normal attendance rate for their schools is 95%

A school district claims that the normal attendance rate for their schools is 95%. An educational advocate believes that the true figure is lower. She chooses a school day in October and chooses 120 random students from the district. On that day, 87.5% of the students attended school.

Can she conduct a hypothesis test to determine whether the proportion of students who attend school is lower than 0.95?

A) Yes, because (120)(0.125) and (120)(0.875) are both at least 10. This means the normal model is a good fit for the sampling distribution.

B) No, because even though (120)(0.95) is at least 10, (120)(0.05) is less than 10. This means the normal model is NOT a good fit for the sampling distribution.
