Q$4(52$ points$)$ Your friend modified the bayesian network to convert it into a decision network.

The Minimum Wage Increase node $($W$)$ is changed to a decision variable. A utility node is also added

that is affected by the political outcome and minimu$$m wage increase. There is a trade$-$off. Increasing

the minimum wage would improve the political outcome, however, it comes with other costs such as

inflation, lay$-$offs, unregistered workers etc. which are all lumped in to the model. The decision network

is given below along with the new conditional probability tables and the utility table.
