Lobster The table gives the numbers ofOctolasmis tridens and O. lowei barnacles oneach of 10 lobsters.8 Does it appear that the barnaclescompete for space on the surface of a lobster?LobsterField Number O. tridens O. loweiAO61 645 6AO62 320 23AO66 401 40AO70 364 9AO67 327 24AO69 73 5AO64 20 86AO68 221 0AO65 3 109AO63 5 350a. If they do compete, do you expect the number x ofO. tridens and the number y of O. lowei barnaclesto be positively or negatively correlated? Explain.b. If you want to test the theory that the two types ofbarnacles compete for space by conducting a test ofthe null hypothesis the population correlation coefficientr equals 0, what is your alternative hypothesis? c. Conduct the test in part b and state your conclusions
