In the epic 1962 battle of the century between everyone's favorite big screen movie monsters, King Kong and Godzilla, Kong went down first but scored a come-from-behind victory when a lightning bolt fueled him with energy. If they had a rematch, who would win? Because of Godzilla's short stubby arms, Kong definitely has the punching advantage because of his long muscular arms. But gorillas can't make a fist like humans can because their fingers are too long, so Kong will have to settle for giving head slaps. And Godzilla can counter by roaring with his atomic breath and swinging his long, lethal tail. Since it appears to be an even fight when the physical characteristics of the foes are considered, how should we determine who would win this monster rematch? Brains over brawn will probably determine the winner. So who is smarter, King Kong or Godzilla? A common approach to measuring intelligence in animals is to compare brain mass and body mass. Animals with larger brain mass relative to their body mass are general thought to be smarter. The Excel file Godzilla's Reptile Cousins shows the body mass and brain mass of 112 reptilian species. The Excel file Kong's Mammal Cousins shows the body mass and brain mass of 95 mammalian species. For both sets of data the scatterplots with body mass as the x-variable and brain mass as the y-variable show that body mass and brain mass are not linearly related. However, for both sets of data, scatterplots show that a linear relationship is appropriate when x = log10(body mass) and y = log10(brain mass). The scatterplots are included in the above Excel files. Question 1. Use the Godzilla's Reptile Cousins file to determine the slope b, and intercept bo of the least squares line y = bo + b1(x) where the x-variable is log10(body mass) and the y-variable is log10(brain mass). intercept (use 5 decimal places) slope (use 5 decimal places) Question 2. Use the Kong's Mammal Cousins file to determine the slope b, and intercept bo of the least squares line y = bo + b1(x) where the x-variable is log10(body mass) and the y-variable is log10(brain mass). intercept (use 5 decimal places) slope (use 5 decimal places) While we don't know the enormous mass of either of the hulking movie monsters, we can use the mass of a large real-life mammal and reptile to obtain comparative values of the brain sizes of King Kong and Godzilla. Question 3a. What is the brain mass in grams of a "small" King Kong whose body mass is 140 kilograms (kg)? grams (use 2 decimal places) Question 3b. What is the brain mass in grams of a "small" Godzilla whose body mass is 180 kilograms (kg)? grams (use 2 decimal places) Question 4. If "brains over brawn" determines the winner, who wins? O Godzilla O King Kong Submit
