A random sample of 100 foxes was examined by a team of veterinarians to determine the prevalence of a particular type of parasite. Counting the number of parasites per fox, the veterinarians found that 69 foxes had no parasites, 17 had one parasite, and so on. A frequency tabulation of the data is given here: What fraction of the parasite counts fall within two standard deviations of the mean?
______________
Within three standard deviations?
______________
Do these results agree with Tchebysheff's Theorem?
______________
With the Empirical Rule?
______________
