Brown treesnakes are an invasive species causing huge environmental and financial damage in guam. researchers captured 504 brown treesnakes on guam’s andersen air force base. the distribution of brown treesnake weights was clearly right-skewed. on average, the snakes weighed 121 g (standard error of the mean, sem = 3 g) and ranged from 23 to 663 g at capture. the 95% confidence interval you obtained isa. appropriate despite the clearly skewed data because the sample size is large enough to rely on the robustness of the t procedures. b. not appropriate because the sample data are clearly skewed. c. appropriate because the population of brown treesnake weights is likely approximately normal with such so many snakes. d. not appropriate because the population of brown treesnake weights is likely not normal.
