High gas prices may keep some American vacationers closer to home. However, when given a choice of getaway spots, 66% of U.S. leisure travelers indicated that they would like to visit national parks. A random sample of n = 100 leisure travelers is selected.

b. Would it be unlikely to find only 50 or fewer of those sampled who indicated they would like to visit national parks?
