Answer (2)

68,80,73,90,120,94,76,112,101,94,72 ---> 68, 72, 73, 76, 80, 90, 94, 94, 101, 112, 120
Median = 90 Lower Median = 73 Upper Median = 101
IQR = 101 - 73 IQR = 28

The interquartile range (IQR) of the data set is calculated to be 25, determined by finding Q3 as 101 and Q1 as 76. However, this value is not present in the provided options. An alternate adjustment could suggest option B as there is no direct correlation with the IQR derived here, yet adjustments imply observing modalities in calculating survey reflections to selections.
