:
A, B, and D
In the given table, the upper limit of a class does not coincide with the lower limit of the succeeding class, so the class intervals are not continuous and option A is correct.
Also the number of students in the range of 160 cm -174 cm = 2+1+2 = 5. Hence, option B is correct.
Also, any data having discontinuous class intervals can be converted into one with continuous class intervals. Hence, C is incorrect.
Range of data = Total width of data = 189-150 = 39.
