In southern California, a growing number of individuals pursuing teaching credentials are choosing paid internships over traditional student teaching programs. A group of thirteen candidates for six local teaching positions consisted of seven who had enrolled in paid internships and six who enrolled in traditional student teaching programs. All thirteen candidates appear to be equally qualified, so six are randomly selected to fill the open positions. Let y be the number of internship trained candidates who are hired. (a) Does...

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...
