Question

part of the population of 4,500 elk at a wildlife preserve is infected with a parasite a random sample of 50 elk shows that 8 of them are infected how many elk are likely to be infected

Answer 1

A total of 720 elk are likely to be infected

Explanation:

we shall be using the proportion by survey to estimate the number of infections

From the survey 8 out of 50 are infected. Thus the likelihood of infection is 8/50

We have 4,500 elk to consider. The number of elk likely to be infected will be 8/50 * 4500 = 720
