In the interest oi iairness to everyone, we will not look at or grade any Precision Tree submission for this problem. For to" credit, you must show all your work; if you use a decision tree, please draw it,- if you use a table or other calculations, please show your work. Assume that expert iniom'Iation about FedEx' price change is available. The expert source would perform analyses on FedEx' pricing policy, and provide a report that is either \"Positive\" or \"Negative\". Historically, when FedEx actually increases its price, the probability this expert produces a Positive report is 30%: when FedEx does not increase its price, the probability that the expert produces a Negative report is SIDE-S.
