A consumer advocate is trying to get legislation passed that will protect the environment of a large city. To increase the probability of success, the advocate re-searches the history of all legislation introduced in the city council in the last 5 years. She records whether the bill was favorable or not favorable to industry, whether the bill was introduced by a member of the city council or by the mayor, and whether it passed or was defeated. These variables are cross-tabulated in the accompanying tables. From these cross-tabulations, whom should the advocate try to persuade to introduce her legislation in the city council? Explain your answer.
