Question 3
Juvenile ground squirrels respond to predators by making alarm calls that can alert others to danger. A biologist conducted a study to investigate how squirrels respond to these alarm calls: run
to burrow or freeze. The biologist played recordings of alarm calls for three samples of ground squirrels, grouped by age, and observed the squirrels' responses. The data for the three age levels
are shown in the table.
