The Australian Journal of Zoology (Vol. 43,1995) reported on a study of the diets and water requirements of spinifex pigeons. Sixteen pigeons were captured in the desert and the crop (i.e., stomach) contents of each examined. The accompanying table reports the weight (in grams) of dry seed in the crop of each pigeon. Find a 99% confidence interval for the average weight of dry seeds in the crops of spinifex pigeons inhabiting the Western Australian desert. Interpret the result.
PIGEONS
.457 | 3.751 | .238 | 2.967 | 2.509 | 1.384 | 1.454 | .818 |
.335 | 1.436 | 1.603 | 1.309 | .201 | .530 | 2.144 | .834 |
