Lobster The table gives the numbers of Octolasmis tridens and O. lowei barnacles on each of 10 lobsters.8 Does it appear that the barnacles compete for space on the surface of a lobster?

a. If they do compete, do you expect the number x of O. tridens and the number y of O. lowei barnacles to be positively or negatively correlated? Explain.

b. If you want to test the theory that the two types of barnacles compete for space by conducting a test of the null hypothesis “the population correlation coefficient r equals 0,” what is your alternative hypothesis?

c. Conduct the test in part b and state your conclusions.
