Researchers have observed that rainforest areas next to clear-cuts (less than 100 meters away) have a reduced tree biomass compared to rain- forest areas far from clear-cuts. To go further, Laurance et al. (1997) tested whether rainforest areas more distant from the clear-cuts were also affected. They compiled data on the biomass change after clear-cutting (in tons/hectare/year) for 36 rainforest areas between 100 m and sev- eral kilometers from clear-cuts. The data are as follows: -10.8, -4.9, -2.6, -1.6, -3, -6.2, -6.5, -9.2, -3.6,-1.8, -1.0, 0.2, 0.2, 0.1, -0.3, -1.4, -1.5, -0.8, 0.3, 0.6, 1.0, 1.2, 2.9, 3.5, 4.3, 4.7, 2.9, 2.8, 2.5, 1.7, 2.7, 1.2, 0.1, 1.3, 2.3, 0.5. These measurements are plotted in the following histogram: Frequency 14- 12- 10- 8- 64 2 0 -12.5 -10 -7.5 -5 -2.5 0 2.5 5 Biomass change Test whether there is a change in biomass of rain- forest areas following clear-cutting. hite the voragious habitatarrow_forwardWhat was the maximum sustained yield under the logistic harvest model when k=500 and r=0.4?
