If numerous large random samples or repetitions of the same size are taken from a population, the frequency curve made from proportions from the various samples will have what approximate shape?

Group of answer choices

A bar graph with two bars, one for the proportion having the trait of interest, and the other for the proportion not having the trait of interest.

A bell-shape.

A flat shape; each outcome should be equally likely.

The shape can't be predicted because it can vary widely depending on the data.
