(a) What population-growth model apparently describes these data?
(b) Calculate the specific growth rate of this population.
(c) What are the proper units for this coefficient?
(d) Why is it unlikely that this mode of growth will be sustained indefinitely?
(e) What model would more appro-priately describe the future behavior of this population?
