Question:

Refer to the Journal of Agricultural, Biological and Environmental Sciences (Sep. 2000) evaluation of the risk posed by hazardous pollutants, Exercise 4.28. In the experiment, guppies (all the same age and size) were released into a tank of natural seawater polluted with the pesticide dieldrin and the number of guppies surviving after 5 days was determined. Recall that the researchers estimated that the probability of any single guppy surviving was .60. If 300 guppies are released into the polluted tank, estimate the probability that fewer than 100 guppies survive after 5 days.


Data from Exercise 4.28

In the Journal of Agricultural, Biological and Environmental Sciences (Sept., 2000), researchers evaluated the risk posed by hazardous pollutants using an ecotoxicological survival model. For one experiment, 20 guppies (all the same age and size) were released into a tank of natural seawater polluted with the pesticide dieldrin. Of interest is Y, the number of guppies surviving after 5 days. The researchers estimated that the probability of any single guppy surviving was .60.
