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. Run to Burrow Freeze Total 1 to 5 Days Old 21 18 39 6 to 15 Days Old 16 24 40 16 to 25 Days Old 12 7 19 Total 49 49 98 If ground squirrels at different ages respond to the alarm signals in the same proportions, what would be the expected count for 6- to 15-day-old squirrels that freeze?

A researcher would like to know whether there is a consistent, predictable relationship between ACT scores and GPA for high school students. A sample of 100 students is obtained from students who took the ACT in their Junior year. Based on the test results and gpa scores, students are classified as high or low for ACT and for GPA. The results are summarized in the following frequency distribution: ACT Score High Low High GPA 39 21 Low GPA 15 25 Based on the data, is there a significant relationship between ACT scores and GPA (α = .05). Compute the appropriate measure of association.
