4.8 Two Discrete Random Varlables: The Binomlal and the Polsson 4.42 A biologist randomly selects 10 portions of water, each equal to .1 cm³ in volume, from the local reservoir and counts the number of bacteria present in each portion. The biologist then totals the number of bacteria for the 10 portions to obtain an estimate of the number of bacteria per cubic centimeter present in the reservoir water. Is this a binomial experiment? Pol. Scl. 4.43 Examine the accompanying newspaper clipping. Does this sampling appear to satisfy the Blo. characteristics of a binomial experiment?
