Hello, I’m stumped on the second portion of this question. I have already solved A: The scores of a sociology test are normally distributed, has a mean of 72.8 points and a standard deviation of 10.5 points.

A) what score is at the 65th percentile? Round to whole numbers (answer is 77 points)

B) above what score is the top 18% of the class? Round to whole numbers.
