Problem: Python eggs. How is the hatching of water python eggs influenced by the temperature of the snake's nest? Researchers placed 104 newly laid eggs in a hot environment, 56 in a neutral environment, and 27 in a cold environment. Hot duplicates the warmth provided by the mother python. Neutral and cold are cooler, as when the mother is absent. The results: 75 of the hot eggs hatched, along with 38 of the neutral eggs and 16 of the cold eggs.16
Required:
(i) Make a two-way table of "environment temperature" against "hatched or not."
(ii) The researchers anticipated that eggs would hatch less well at cooler temperatures. Do the data support that anticipation?
