Velvetleaf is a particularly annoying weed in corn fields. It produces lots of seeds, and the seeds wait in the soil for years until conditions are right. How many seeds do velvetleaf plants produce? Given are counts from 28 plants that came up in a corn field when no herbicide was used.
2450 | 2504 | 2114 | 1110 | 2137 | 8015 | 1623 | 1531 | 2008 | 1716 |
721 | 863 | 1136 | 2819 | 1911 | 2101 | 1051 | 218 | 1711 | 164 |
2228 | 363 | 5973 | 1050 | 1961 | 1809 | 130 | 880 |
We would like to give a confidence interval for the mean number of seeds produced by velvetleaf plants. Alas, the interval can not be safely used for this data. Why not?
It is because of the fact that the standard deviation of the population is not given.
It is because of the fact that the mean of the population is not given.
It is due to high outliers.
It is because the sample is too small.
