Use the information from Problem 12 in Chapter 8. Assume you are given the authority and the appropriate funds to correct the problem. You can spend:

i) $50 to replace batteries in all CO monitors annually to reduce that probability to 0.0

ii) $500 on electricity over the holidays to maintain ventilation and reduce that probability to 0.0

iii) $5,000 to replace the flue and reduce that probability to 0.0

Which one alternative is most cost effective? Which one alternative would you recommend? Why?
