Order the data from low to high

 

(30, 32, 33, 36)   ( 37, 40, 40, 46)

 

The 3rd quartile  = median of second data grouping  =  40      (1)

The 1st quartile  = median of first data grouping = [32 + 33] / 2 = 65/ 2  =  32.5     (2)

 

The interquartile range  =  (1) - (2) =  40 - 32.5   =   7.5  ⇒  "B"
