Question: Python eggs, again. Exercise presents data on the hatching of python eggs at three different temperatures. Does temperature have a signifi- cant effect on hatching? Write a clear summary of your work and your conclusion.
Exercise: Python eggs. How is the hatching of water python eggs influenced by the temperature of the snake's nest? Researchers assigned newly laid eggs to one of three 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:
Eggs Hatched
Cold 27 16
Neutral 56 38
Hot 104 75
(a) Make a two-way table of temperature by outcome (hatched or not).
(b) Calculate the percentage of eggs in each group that hatched. The researchers anticipated that eggs would not hatch in the cold environment. Do the data support that anticipation?
