How to calculate the 70th percentile with a mean and standard deviation?
Using a dataset with mean = 77 and SD = 5.41, find the exam score for student who is at the 70th percentile (did better than 70% of students).
I have a chart for z scores and know how to convert raw scores to p-values or z-scores and vice versa but I am not sure how to calculate this. Also If 77 is the mean and its the 50 percentile then two standard deviations would be the 70th?
