The best way to deal with this kind of question is to convert cumulative number to relative. 0-2 29 2-5 17 6-8 8 9-11 4 12-14 2 It is clear from here that the asnwer should be 46 |

Convert to absolute frequency for clarity, not relative frequency (which is in percentage form). |

If you look at the chart, you will find that the total amount of occurrences equal 60. Therefore, the answer will be definitely <= 60. Hence A. No calculation needed. |
