Python eggs, I How is the hatching of water python eggs infl uenced by the temperature of the snake’s nest? Researchers assigned newly laid eggs to one of three water temperatures: hot, neutral, or cold. Hot duplicates the extra warmth provided by the mother python, and cold duplicates the absence of the mother.

Here are the data on the number of eggs and the number that hatched:

(a) Make a two-way table of temperature by outcome (hatched or not).

(b) Calculate the percent of eggs in each group that hatched. Th e researchers anticipated that eggs would not hatch in cold water. Do the data support that anticipation?

Eggs Hatched Cold 27 16 Neutral 56 38 Hot 104 75
