It’s been found that 85% of American adults suffer from triskaidekaphobia (fear of the number 13). Researchers think this is too low and were interested to know if triskaidekaphobia has economic implications for large high-rise hotels. A USA Today/Gallup poll conducted February 9 – 11, 2007 asked 1,006 randomly selected people 18 years old and older in telephone interviews “Suppose you checked into a hotel and were given a room on the thirteenth floor. Would this bother you or not?” 87% of the survey respondents answered they would be bothered. Test the researchers’ claim at the 0.1 level of significance.

What are the correct null and alternative hypotheses?
