The undergraduate grade point averages (UGPA) of students taking an admissions test in a recent year can be approximated by a normal distribution, as shown in the figure.
**Questions:**
(a) What is the minimum UGPA that would still place a student in the top 15% of UGPAs?
(b) Between what two values does the middle 50% of the UGPAs lie?
**Diagram Explanation:**
The diagram shows a normal distribution curve representing the UGPA scores. The mean (µ) is 3.38, and the standard deviation (σ) is 0.21. The x-axis, labeled "Grade point average," ranges from 2.76 to 4.0. Vertical lines mark one standard deviation below and above the mean.
**Solution Prompt:**
(a) The minimum UGPA that would still place a student in the top 15% of UGPAs is _____.
(Round to two decimal places as needed.)
