A logistic regression model was proposed for classifying common brushtail possums into their two regions. The outcome variable took value 1 if the possum was from Victoria and 0 otherwise. Estimate SE Z Pr(>[ZD) Intercept) 32.4366 9.9472 3.2609 0.0012 sex male -1.3114 0.6412 -2.0452 0.0408 skull width -0.2798 0.1275 -2.1945 0.0282 total length 0.5634 0.1228 4.5879 0.0002 tail length -1.8161 0.3544 -5.1244 (a) Write out the form of the model. og_odds(Victoria) = 32.4366 v+ -1.3114 sex_male + -0.2798 skull_width + 0.5634 total_length + -1.816 tail_length Also identify which of the variables are positively associated when controlling for other variables. Osex male skull width Otail_length total_length (b) Suppose we see a brushtail possum at a zoo in the US, and a sign says the possum had been captured in the wild in Australia, but it doesn't say which part of Australia. However, the sign does indicate that the possum is male, its skull is about 60 mm wide, its tail is 37 cm long, and its total length is 82 cm. What is the reduced model's computed probability that this possum is from Victoria? 0.113
