A Large Fishing Farm with Thousands of Fish Has Been

Multiple Choice

A large fishing farm with thousands of fish has been treating its fish to stop a spreading fungal infection. A simple random sample of 50 fish is taken to determine the proportion p that is infected in this population. A careful examination determines that 6 of the fish sampled are infected. The infection would be contained if fewer than 10% of the fish were infected. To answer this question, which null and alternative hypotheses would we test?

A) H₀:p = 0.50, H_a:p < 0.50
B) H₀:p = 0.12, H_a:p < 0.12
C) H₀:p = 0.12, H_a:p < 0.10
D) H₀:p = 0.10, H_a:p < 0.10
