Question
A veterinary study of horses looked at water sources for horses, and the investigators found that horses received water from a well, from city water, or from a stream. The investigators wanted to know if horses are equally likely to get water from each of those three sources. They collected data and observed the given values.
Water Source | Well | City Water | Stream | Total |
Observed count | 62 | 43 | 31 | 136 |
The cell that contributed least to the chi-square goodness-of-fit statistic is:
- The city water cell with = 0.1201
- The well water cell with = 6.13
- The stream water cell with = 0.1201
- The city water cell with = 1/3
