question 106

Not Answered

The limitation imposed on population density by environmental factors is poorly understood.One theory is that terrestrial carnivores are particularly sensitive to the food supply.Spiders are very important species in terrestrial communities, and their survival is ecologically important.To better understand the relation between food level and spider survival, an experiment was conducted by supplementing the food supply of immature spiders in an area of low population density.In a control group of immature spiders, 83 out of 112 survived to the end of the experiment; in the food- supplemented experimental group, 76 out of 81 survived.The 90% confidence interval for the difference in population proportions is:
