Calculate the value of the following from Krukowski et al. Under the section Intervention efficacy, it says LYG were discounted at a rate of 3% for a period of 33.8 years representing the average age of the participants and life expectancy for the average person. In other words, based on Table 4, the intervention increases life expectancy by 0.469 years at the end of a 33.8 year period for the internet intervention. Use this information to calculate discounted LYG for internet and in-person using undiscounted LYG in Table 4. Show your calculations! Show the calculations for the C-E ratio (discounted) for Internet, In-person, and Incremental from Table 4
