Answer

Explanation:

Step1: Calculate lower - bound

Subtract the margin of error from the estimate. The estimate is 75% and the margin of error is 5%. So, $75 - 5=70$.

Step2: Calculate upper - bound

Add the margin of error to the estimate. So, $75 + 5 = 80$. The true proportion of students who work while in school is likely to be between 70% and 80%.

Answer:

A. Between 70% and 80% of the students at Aria's college work while they're in school.
