its been such a long time but i remembet that interquartile range i3 3rd quartile-first quartile

OpenStudy (welshfella):

i think first quartile is 35 and 3rd is 49

OpenStudy (welshfella):

not sure though

https://www.mathsisfun.com/data/quartiles.html OK so first you have to put the numbers in order 31, 33, 35, 41, 43, 46, 48, 49, 49, 50 Then you have to cut the list into quartiles.. Lower Quarter here is 35.. Middle Quartile here is in between 43 and 46 so 66 (Add and divide by 2) Upper Quartile is 49 49 - 35 = 14 SO your answer is D :)
