I need tо estimаte the pоpulаtiоn of а “NPR” type wine and cheese dinner party. I hide in the bathroom for a set time period and catch 15 individuals entering the restroom either to use it properly or hide in there as they use their phones to search the internet to prove Mark wrong (Mark is such an arrogant A-hole). I mark them by placing a democratic party pin on them. I return the next weekend and capture 20 individuals with 16 wearing my democratic pins. What is the size of the population? (worth 10) Formulas needed: Mark-recapture M/N = R/C N= (MC)/R N= population size M = marked individual C = number of individuals in second sampling R = number of recaptures Ro = ∑ lxbx lx = survivorship (proportion of organisms surviving from start of life table to age x) nx = number of individuals sx= Survival rate bx = fecundity (Number of offspring produced by females of age x) T= ∑ xlxbx /∑ lxbx
