This exercise uses the population growth model. A grey squirrel population was introduced in a certain county of Great Britain 35 years ago. Biologists observe that the population doubles every 7 years, and now the population is 100,000. (a) What was the initial size of the squirrel population? squirrels (b) Estimate the squirrel population 10 years from now. (Round your answer to the nearest whole number.) squirrels (c) Sketch a graph of the squirrel population. (Assume t = 0 corresponds to the initial introduction.) n(t) n(t) 500000 500000 400000 400 000 300000 300000 200000 200000 100000 100000 10 20 30 40 50 10 20 30 40 50 n(t) n(t) 500000 500 000 400000 400 000 300000 300000 200000 200 000 100000 100000 10 20 30 40 50 10 20 30 40 50

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.
