An electric utilities company must choose between two technology options for generating electricity for its customers in the future: coal or nuclear energy. In order to assess the attitudes of local citizens, the power company conducted a public opinion poll. Four sectors were considered: news media, coal miners' union, environmentalists and conservationists, and local groups. Fifty (50) persons were randomly sampled from each sector and asked to give their opinions. The results of the survey are shown in the table below: Coal Environmentalists News Media Miner's and Local Groups Total Union Conservationists Support Coal Option 21 42 11 25 99 Support Nuclear 18 2 16 13 49 Option Neutral 11 23 12 52 Totals 50 50 50 50 200 Construct a 90% two-sided confidence interval for the percentage of environmentalists and conservationists who support the nuclear option. What is the upper confidence limit?
