Question
47.
For numbers 45-49: McDonald (1985) counted allele frequencies at the mannose-6-phosphate isomerase (Mpi) locus in the amphipod crustacean Megalorchestia californiana, which lives on sandy beaches of the Pacific coast of North America. There were two common alleles, Mpi90 and Mpi100. He wants to determine the effect of focation (measured in latitude) in the presence of Mpi100. The data were divided into testing and training sets. The result of regression analysis is X²-83.3, di-1. p-value-7x10-20 and the equation of the relationship is in (1) 7.5469 + 0.1786 latitude The said regression was fitted to test set and obtained the following confusion matrix Predicted Probability Outcome cut-off cut-off Not Mpi100 42 11 Mpi100 18 29
