# $15($p$\mathrm{.}157)$ Policy relevant problem

# $27($pp$\mathrm{.}163-164)$ Similar to the marketing example discussed in class. A realistic condition is added: Exposed population is divided by Sex and Age.

For the selected problems perform Sensitivity analysis, and explain the results of the sensitivity analysis $($not more than three$-$five sentences for each of two$)$
