Step 1: 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 is a two-way table of temperature by outcome (hatched or not) is given:
Fill in the blanks: (Give your answers to one decimal place.)
a. The percentage of hatched eggs at the cold temperature is ___.
b. The percentage of hatched eggs at the hot temperature is ___.
Step 2:
The researchers anticipate that eggs are less likely to hatch in the cold environment.
State whether the researchers’ anticipation is true or false.
Explanation / Answer
Total eggs = 187
a)
The percentage of hatched eggs at the cold temperature is = 16/187 = 8.5%
b)
The percentage of hatched eggs at the hot temperature is = 75/187 = 40.1%
The researchers anticipate that eggs are less likely to hatch in the cold environment.
