You set up a series of cameras along the Mexican border. The rate of appearances of Jaguars is 4/18 years. Your cameras also produce pictures of wolf-sized canids, either wolves or coy-wolves in the same region. Each year your cameras catch about 400 of these animals, about 60 cougars and about 700 bears and 1200 feral hogs. Assume that these numbers are all population rates for Poisson. Given your cameras catch a non human large animal (and the above list is all of them): i. What is the probability it is a jaguar? (Hint: Animals are independent. This is asking the conditional probability of a jaguar, given you see an animal) ii. What is the probability it is a feral hog? iii. Out of 25 large nonhuman animals, what is the probability that 15 or more are feral hogs? (Hint N=25, P is fixed, independent trials) iv. Out of 180 large non human animals what is the probability that between 100 and 170 are feral hogs?
Contingency Table
A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.
Binomial Distribution
Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.
