For two species A and B in competition, the carrying capacities, competition coefficients, per capita growth rate and population size are

KA = 1000           KB = 1200    α of B= 1     β of A= .5       rB= .5         r A= .3                

AN= 500                  BN= 200

A test to screen for a serious but curable disease is similar to hypothesis testing, with a null hypothesis of no disease, and an alternative hypothesis of disease. If the null hypothesis is rejected treatment will be given. Otherwise, it will not. Assuming the treatment does not have serious side effects, in this scenario it is better to increase the probability of:
