The diet of peregrine falcons consists of songbirds, shorebirds, and waterfowl. Typically, songbirds are smaller than shorebirds, which are smaller than waterfowl. The female peregrine is considerably larger than the male, with a length of 46-54 cm, compared to 38-46 cm for the male. Data were collected on the prey of a number of peregrines of each sex for the purpose of determining whether or not the larger females more regularly capture the larger prey, with the results below.

Prey Type
Songbirds	Shorebirds	Waterfowl
Male	17	9	5
Female	12	12	10

Use a statistical test to assess whether there is an association between sex and prey type.

What is the null hypothesis for the test?

There is no difference in prey type between male and female falcons.

The distribution of prey type is heterogeneous for male and female falcons.

The distribution of prey type is not homogeneous for male and female falcons.
