Hi.
This homework problem has me completely lost;
Which of the following is true?
(a) D5 = P5 = Q5
(b) D50 = P5 = Q25
(c) D5 = P50 = Q2
(d) D50 = P5 = Q2
I think that Q represents Quartiles, and P represents Probability, but I can't find in the text what D represents. I don't have any idea what formula I could use to find the correct answer. Thank you for any help you can give!
