In February 8, 2002, Gallup Organization released results of poll concerning Americans attitudes toward 19th Winter Olympic Games in Salt Lake City, Utah. Poll results were based on telephone interviews with arbitarily chosen national sample of 1,011 adults, 18 years and older, conducted February 4-6, 2002.
Assume we wish to use poll's results to justify claim that more than 30 percent of Americans (18 years or older) say that figure skating is their favorite Winter Olympic event. Poll really found that 32% of respondents reported that figure skating was their favorite event. If, for sake of argument, we suppose that 30% of Americans (18 years or older) say figure skating is their favorite event (that is, P = .3), compute probability of observing sample proportion of .32 or more; that is P(p >.32).
Based on probability you calculated in part a, would you conclude that more than 30 percent of Americans (18 years or older) say that figure skating is their favorite Winter Olympic event?
