A large fishing farm with thousands of fish has been treating its fish to stop a spreading fungal infection. A simple random sample of 150 fish is taken and a careful examination determines that 12 of the fish sampled are infected. The infection would be contained if fewer than 10% of the fish were infected. Which test statistic would we use for the test? MSG OF = MSE (0-E)* x² = z = Po(1-Po Ot= s/Vn
