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. (Intercept) sex_male skull_width total_length tail_length Estimate 34.5947 -1.3795 -0.2762 0.5538 -1.8227 SE 9.9311 0.6455 0.1291 0.1298 0.364 Z 3.4835 -2.1371 -2.1394 4.2666 -5.0074 Pr(> [21) 0.0004 0.0326 0.0324 0 0 (a) Write out the form of the model. log_odds(Victoria) - skull_width + sex_male + total_length + tail_length Also identify which of the variables are positively associated when controlling for other variables. tail_length total_length skull_width sex_male (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 female, its skull is about 61 mm wide, its tail is 40 cm long, and its total length is 78 cm. What is the reduced model's computed probability that this possum is from Victoria?
