Question
In our initial survey, the guess at the mean age for the class had a mean of 21.9 and a standard deviation 3.03.
Using this information, what would be the first and third quartile be for the class? ( P(Z<.25) and P(Z<.75) respectively)
I think you use the Z score formula to find the "X" values or construct an assemblage of data points to find the min, max, med, and Q1 and Q3? i've been stuck on how to solve it for day's.. i just don't get it. thank you for your feedback
