Example 34
setosa flowers in the population is estimated to be 0.333. (It should be pointed out that
it was by design that the sample contained equal numbers of setosa, versicolor, and
virginica flowers. It is therefore not meaningful in this example to draw inferences
about population proportions from the sample. Nevertheless, we will treat species here
as a random variable in order to demonstrate how such inferences can be made.)
