2. Juvenile free-living ground squirrels utilize responses known as "alarm calls" in response topredators. These calls can alert others to danger. Newly weaned squirrels emerge from the nest atabout 25 days of age. Do the squirrels emerge with automatic responses to alarm signals, or are theresponses learned? To answer this question, a biologist played recordings of alarm calls for threerandom samples from populations (by age) of squirrels and observed the squirrels' responses. Shereasoned that if the responses were not different for the different age groups, the squirrels must beresponding by instinct. On the other hand, if the responses differ with the age of the squirrels theyoung squirrels must be learning to respond to the alarm calls. Her data for the responses,categorized by age, is presented below:Response to alarm callEnter orStand up orrun to burrowfreezeTotalsDays since weaning1-52118396-1016244010-151219Totals494998Is there convincing evidence that the response to an alarm call is different for the different agegroups?
