Question: "Hoping to protect wildlife and the natural sights and sounds of Yellowstone and Grand Teton, the National Park Service has decided to phase out the use of snowmobiles in both parks" ( Orlando Sentinel , November 24, 2000; reference 13). Business owners in Montana and Wyoming are concerned about the economic impact of this phase-out that is to be completed by winter 2003. Assume that in a random sample of 320 visitors to these parks 180 agreed with this plan to phase out the snowmobiles. Estimate the population proportion of visitors who support this phase out. Is it possible to say at 95% confidence level, that more than one half of the visitors agree with the plan? And at 99% confidence level?
