| stevelaz | I jumped in and just added the 60+31 = 91...that will teach me to read the question....it said Cumulative !...doh |
| surob | 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 |
| octavianus | Convert to absolute frequency for clarity, not relative frequency (which is in percentage form). |
| Yurik74 | surob - thanks, good approach |
| Majumba | Is this correct?The answer should have been 31 |

| dquang225 | 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. |
