In mark-recapture studies a certain number of individuals in a population are captured, tagged, and then released. The population is then sampled again, and the fraction of tagged individuals in the sample (That is, the fraction of individuals in the sample that have been ‘recaptured’) is used to estimate the population size. Suppose 4 moose out of a population of 20 are captured, tagged, & released. If 4 individuals from this population are then subsequntly captured, what is the probability...

Plains Wanderer samples were collected from two points in time. A pre-clearing historic sample was collected from feathers stored in a museum collection. This historic sample included 40 samples from a collection of specimens shot in 1955 at a single population near Warracknabcal. Victoria. A post-clearing contemporary sample was collected in 2015 from the same...

Vitamin D, whether ingested as a dietary supplement or produced naturally when sunlight falls upon the skin, is essential for strong, healthy bones. The bone disease rickets was largely eliminated during the 1950s, but now there is concern that a generation of children more likely to watch TV or play computer games than spend time outdoors is at increased risk. A healthcare provider took a sample of 285 randomly selected children and found 20% of them were deficient in vitamin...

Since the 1980s, HIV (Human Immunodeficiency Virus) has been infecting humans around the world causing the condition known as AIDS (Acquired Immune Deficiency Syndrome). HIV, like all viruses, needs to enter cells and use their machinery to reproduce and spread. During HIV infection, the virus enters specific cells of the immune system (T-cells) by "docking" onto cell surface proteins, including one called CCR5 Genetic analysis of individuals who are naturally immune (resistant) to HIV have revealed that resistance to HIV...
