[AI-generated answer — Bot GPT 3.5]

To find the percentage of students who scored above 180 on the Advanced Algebra final exam, we need to calculate the z-score for 180 and then find the percentage of scores above that z-score.

First, calculate the z-score:

z = (x - μ) / σ
z = (180 - 150) / 15
z = 2

Next, we find the percentage of scores above a z-score of 2 in a standard normal distribution table, which is approximately 2.28%. This means that approximately 2.28% of the students who took the test scored above 180.
