One of the problems with the capture-recapture method is that in some animal populations there are individuals that are trap-happy (easy to trap) and others that are more cagey and hard to trap. Too many trap-happy individuals can skew the data (see Exercise 62 ). A removal method is a method for estimating the N-value of a population that takes into account the existence of trap-happy individuals by trapping them and removing them. In the first “capture,” individuals from the general population are trapped, counted, and removed from the habitat so that they can't be trapped again. In the “recapture,” individuals from the remaining population (those that had not been trapped before) are trapped and counted. The number of individuals trapped in the capture can be denoted by

- In a town with 5000 adults, a sample of 50 is selected using SRSWOR and asked their opinion of a proposed municipal project; 30 are found to favor it and 20 oppose it. If, in fact, the adults of the town were equally divided on the proposal, what would be the probability of observing what has been observed? Approximate using the Binomial distribution. Compare this with the exact probability which is 0.0418.arrow_forward1.2.19. Let and s be natural numbers. Let G be the simple graph with vertex set Vo...
