A group of wildlife biologists studied a chipmunk population in a 3000 hectare forest from 1940 to 1995. Estimates of the size of the population (rounded off to the nearest to) are shown in the table below a. Graph the change in size of the population from 1940 to 1995.

b. What was the population density of chipmunks in 1970?

c. What was the average change in the population density from 1940 to 1960?

d. What was the average change in population from 1960 to 1985?

e. A biologist thinks the population of chipmunks will be in the range of 2900 to 3100 in the year 2000. Is that a reasonable guess? Why or why not?
