Refer to Exercise 26.

a. Of the eggs that hatched, what proportion were randomly assigned to hot water?

b. Of the eggs that were randomly assigned to hot water, what percent hatched?

c. The segmented bar graph displays the distribution of hatching status by water temperature. Describe what this graph reveals about the association between these two variables for the python eggs in this experiment.

Exercise 26.

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. The two-way table summarizes the data on whether or not the eggs hatched.
