If birth rate < death rate, population size increases
If death rate < birth rate, population size decreases
If birth rate > death rate, population size increases
If death rate > birth rate, population size increases
The population sample equals the number marked multiplied by the sum of the unmarked and recaptured divided by the number recaptured
The population sample equals the number marked minus the sum of the unmarked and recaptured divided by the number recaptured.
The population sample equals the number marked divided by the number recaptured
The population sample equals the number unmarked plus the recaptured divided by the number recaptured
Indirect observation may be used when a population is small or difficult to find.
Indirect observation may be used when a population is located in a remote area that the scientist cannot get to.
Indirect observation may be used to mark and recapture organisms.
Indirect observation may be used for sampling.
There would be a population of 66 mice.
There would be a population of 225 mice.
There would be a population of 116 mice.
