On february 15, 2012, students in stt 201 at michigan state university were asked "how old were you on your last birthday? their responses are tallied in the table below: age: 18 19 20 21 22 25frequency: 102 297 95 111 47 48 find the iqr of the age distribution.

3

Step-by-step explanation:

IQR = Median upper range - Median lower range

     =  22 - 19
