Otitis media, or middle ear infection, is initially treated with an antibiotic. Researchers have compared two antibiotics, A and B, for their cost effectiveness. A is inexpensive, safe, and effective. B is also safe. However, it is considerably more expensive and it is generally more effective. Use the tree diagram to the right (where the costs are estimated as the total cost of medication, office visit, ear check, and hours of lost work) to answer the following. a. Find the expected cost of using each antibiotic to treat a middle ear infection. A tree diagram has a root that splits into 2 branches labeled A and B. Primary branch A splits into 2 secondary branches labeled 0.80 Cure 59.30 dollars and 0.20 No cure 96.15 dollars. Primary branch B splits into two secondary branches labeled 0.90 Cure 69.15 dollars and 0.10 No cure 106.00 dollars.0.800.200.900.10 b. To minimize the total expected cost, which antibiotic should be chosen? a. The expected cost of using antibiotic A is $nothing. (Round to the nearest cent as needed.)
