Question

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.

True False Eggs Hatched Cold 27 16 Neutral 56 38 Hot 104

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.
