Step 1 :The problem is about a hypothesis test where the president of a junior college believes that the proportion of students who earn a bachelor's degree within six years at her institution is higher than 0.389.
Step 2 :A Type I error, also known as a false positive, occurs when we reject a true null hypothesis.
Step 3 :In this context, a Type I error would mean that we conclude that the proportion of students who earn a bachelor's degree within six years at the president's institution is higher than 0.389, when in reality it is not.
Step 4 :\(\boxed{\text{Final Answer: A Type I error in this context would mean that we conclude that the proportion of students who earn a bachelor's degree within six years at the president's institution is higher than 0.389, when in reality it is not.}}\)
