For Numbers 12 and 13: A particular concentration of a chemical in polluted water has been found to be lethal to 20% of the fish that are exposed to the concentration for 24 hours. To further study this, twenty tanks containing five fish each with this concentration of chemical in water were prepared, and the number of dead fish after 24 hours was recorded. At alpha-5%, verify if the data fits a binomial distribution with p=0.2 Number of dead fish 0 Observed (O) 1 2 3 4 5 2 3 1 8 5 1 2. Under the hypothesized probability distribution, the expected frequency of one dead fish is A. 1.000 B. 2.048 C. 4.000 D. 8.192
