Question

Part of the population of 5,500 elk at a wildlife preserve is infected with a parasite. A random sample of 50 elk shows that 6 of them are infected. How many elk are likely to be infected? Based on the sample, there will likely be infected elk in the wildlife preserve.​

Answer 1

x = 660

Explanation:

Solve

• Write the proportion where x is the number of infected elk

6/50 = x/5,500

• Cross multiply

5500 ÷ 50 = 1100 x 6

x = 660

Answer 2

5444

Explanation:

5,500-50=5,450

5,450-6=5,444
