1. A public health official in Tennessee wants to know the difference of COVID-19 mortality rate between the States of Tennessee and New York as of April 8, 2020. Of 4,362 confirmed cases in Tennessee, 79 deaths reported with a mortality rate of 1.8% or 0.018 (79/4362). Of 149,401 confirmed cases in New York, 6,268 deaths reported with a mortality rate of 4.2% or 0.042 (6,268 /149,401). Is the COVID-19 mortality rate of Tennessee significantly less than that of New...

A state department of health is considering a public awareness campaign to encourage vaccination. It determines that the cost of this campaign would be $700,000 per year for the next 6 years. It estimates that the campaign would reduce rates of illness and communicable disease. At the end of the first year of the campaign, the resulting savings would be $1,300,000; the savings would decrease by $80,000 each of the following 5 years. Assuming a discounting factor of 4%, compute...
