Question 678426
I need to find the first and second quintiles (20th and 40th percentiles) of the data shown here: 
52 61 88 43 64
71 39 73 51 60 
-----
20^ of 10 = 2
----
The 3rd element from the minimum has 20% of the data below it
20%ile = 51
-----
The 5th element has 40% of the data below it
40%ile = 60
==================
The TI-84 will rank the data but will not calculate quint's and deci's
===================
