Given
n = 256 μ = 17 St.Dev = 80 μ X = 22
Find the Standard Error
S E = σ n = 80 256 = 5
Find the z-score
z = 17 22 5 = 1

I want to apply to a university where the 25th /75th percentiles for the SAT Math are 490 / 620 respectively, but I am curious how would I find the mean and the standard deviation assuming that the data is normally distributed? I know that we are talking about the middle 50th-percentile and z 0.25 = 620 and z 0.75 = 490
