To list the seven fastest times from least to greatest, we need to consider the information provided:
- The fastest marathon time is 2:03:59, set by Haile Gebrselassie from Ethiopia on Sept 28, 2008.
- The mean time for seven of the fastest marathons is 2:04:34.
- The median time is 2:04:27.
- The mode time is 2:04:27.
- The range of times between the fastest and seventh fastest times is 57 seconds.
- The two times between the median and the seventh fastest times are 2:04:53 and 2:04:55.
Considering this information, we can list the seven fastest times from least to greatest as follows:
1. 2:04:55
2. 2:04:53
3. 2:04:27 (median and mode times)
4. 2:04:27 (median and mode times)
5. 2:04:34 (mean time)
6. 2:06:32 (Samuel Kamau Wansiru's time at the 2008 Beijing Summer Olympics Marathon)
7. 2:03:59 (fastest time, set by Haile Gebrselassie)
Please note that the first two times, 2:04:55 and 2:04:53, are between the median and the seventh fastest times, so they are included in the list.
