Python eggs How is the hatching of water python eggs influenced by the temperature of the snake’s nest? Researchers randomly 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 that hatched and didn’t hatch:15 Water Temperature Hatched? Cold Neutral Hot Yes 16 38 75 No 11 18 29

(a) Compare the distributions of hatching status for the three treatments.

(b) Are the differences between the three groups statistically significant? Give appropriate evidence to support your answer.
