In the example provided, the quartiles are:
25% = 16.5 (the median of {15, 16, 17, 18})
50% = 18.5 (the median of {15, 16, 17, 18, 19, 20, 21, 22})
75% = 20.5 (the median of (19, 20, 21, 22})
The 25th multiple of 15 is 375.
28 is the 3rd quartile.
1.5
50 is 100*50/15 percent of 15. That is 333.33... recurring %.50 is 100*50/15 percent of 15. That is 333.33... recurring %.50 is 100*50/15 percent of 15. That is 333.33... recurring %.50 is 100*50/15 percent of 15. That is 333.33... recurring %.
15 percent of 11.19 is 1.67. Or 11.99 minus 15 percent is 9.52.
