Question: Size of Hunting Parties In the 1960s, the famous researcher Jane Goodall observed that chimpanzees hunt and eat meat as part of their regular diet. Sometimes chimpanzees hunt alone, while other times they form hunting parties. The following table summarizes research on chimpanzee hunting parties, giving the size of the hunting party and the percentage of successful hunts.

a. Plot the data. Do the data points lie in a linear pattern?

b. Find the correlation coefficient. Combining this with your answer to part a, does the percentage of successful hunts tend to increase with the size of the hunting party?

c. Find the equation of the least squares line, and graph it on your scatterplot.

d. Find the equation for the least squares line for the data.

e. Use the results of part a to determine how many chirps per second you would expect to hear from the striped ground cricket if the temperature were 73°F.

f. Use the results of part a to determine what the temperature is when the striped ground crickets are chirping at a rate of 18 times per sec.

g. Find the correlation coefficient.
