Final answer:
The question pertains to the normal distribution of gorilla lifespans in zoos, specifically the mean lifespan of 20.8 years and a standard deviation of 3.1 years, which is related to biology and statistics within the context of animal behavior and conservation.
Step-by-step explanation:
The lifespan data of gorillas in a zoo that follows a normal distribution with a mean (average) lifespan of 20.8 years and a standard deviation of 3.1 years is an example of statistical analysis within the field of biology, more specifically, zoology and ethology (the study of animal behavior). By examining this data, biologists can assess the health and well-being of gorillas in captivity compared to their wild counterparts and analyze factors influencing their longevity. Gorillas, which are part of the great apes along with chimpanzees, orangutans, and humans, have complex social structures and reproductive patterns. This knowledge provides insight into the survival and reproductive success of these primates under zoo conditions.
Great apes, including gorillas, are characterized by extended care for their young, with a gestation period of 8-9 months and long adolescent periods before maturity. These factors are important in managing captive populations, as they contribute to the overall life expectancy of the species. Moreover, gorilla populations are threatened in the wild due to poaching, habitat loss, and disease, which makes conservation efforts in zoos crucial for their sustainability. Understanding the life expectancy and mortality rates of gorillas in captivity also aids in the development of better conservation strategies for endangered species like the mountain gorillas.
