Question
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.
 
​(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?

Using the browser's print will lead to an undesirable print-out. Use the Print item from the "Question Help" menu to get a better print-out.

**Graph Description:**

The graph presented is a standard normal distribution curve representing grade point averages (GPA). The x-axis is labeled "Grade point average," with values ranging from 2.6 to 4.0. The peak of the curve is at a GPA of 3.30, denoted by the mean symbol \( \mu = 3.30 \). The standard deviation is indicated by \( \sigma = 0.16 \).

The distribution is symmetrical, with the highest point at the mean, suggesting that most students have an average GPA around 3.30. The curve tails off symmetrically on both sides, approaching zero as it moves away from the mean, representing fewer students with GPAs significantly lower or higher than 3.30.

**Action:**
Press "OK" to proceed.
