Hint(s) Check My Work Freelance reporter Irwin Fletcher is examining the historical voting records of members of the U.S. Congress. For 175 representatives, Irwin has collected the voting record (yes or no) on 16 pieces of legislation. To examine the relationship between representatives' votes on different issues, Irwin has conducted an association rules analysis with a minimum support of 40% and a minimum confidence of 90%. The data included the following bills: • Budget: approve federal budget resolution • Contras: aid for Nicaraguan contra rebels • El_Salvador: aid to El Salvador • Missile: funding for M-X missile program • Physician: freeze physician fees • Religious: equal access to all religious groups at schools • Satellite: ban on anti-satellite weapons testing The following table shows the top five rules with respect to lift ratio. The table displays representatives' decisions in a "bill-vote" format. For example, "Contras- y" indicates that the representative voted yes on a bill to support the Nicaraguan Contra rebels and "Physician-n" indicates a no vote on a bill to freeze physiciar fees. Antecedent Consequent Support for A and C Confidence Lift Ratio Contras-y, Physician-n, Satellite-y El_Salvador-n 0.40 0.95 1.98 Contras-y, Missile-y El_Salvador-n 0.40 0.91 1.90 Contras-y, Physician-n El_Salvador-n 0.44 0.91 1.90 Missile-n, Religious-y El_Salvador-y 0.40 0.93 1.79 Budget-y, Contras-y, Physician-n El_Salvador-n 0.41 0.90 1.89
