1.

You are doing a mark-recapture experiment to determine the population size of the MendAliens living on an island in my back yard. Initially, you catch and mark 130 MendAliens, which you then release. Next, you capture 90 MendAliens, of which 20 are marked. What is your estimate of the population size of MendAliens living on the island in my back yard? (Activity 52A)

pyramid
inverted pyramid
a rectangle tapering toward the top
both a pyramid and a rectangle tapering toward the top result in a population that decreases in size
both an inverted pyramid and a rectangle tapering toward the top result in a population that decreases in size
