A grouped frequency distribution table with class intervals of equal size using 250 - 270 (270 not included in this interval) as one of the class intervals is constructed for the following data :
268, 220, 368, 258, 242, 310, 272, 342, 310, 290, 300, 320, 319, 304, 402, 318, 406, 292, 354, 278, 210, 240, 330, 316, 406, 215, 258, 236.
The frequency of class 310 - 330 is

Answer
Elements from above data in the class 310 - 330 are :
310, 310, 320, 319, 318, 316.
Hence, the frequency of class 310 - 330 is 6.
Hence, Option 3 is the correct option.
