Executives from Six Flags, a well-known amusement park chain, had interest in constructing a Six Flags theme park in a location near Ames city limits. Experts believed that approximately 15% of the surrounding population would be interested in becoming season ticket holders. A random sample of 500 residents of Story County was collected (of the approximately 80,000 residents of Story County). Of the 500 people sampled, 124 said that they would be interested in purchasing season tickets to a Six Flags in Ames.
Suppose another random sample of 500 residents of Story County was collected. The sample proportion of people who would be interested in purchasing season tickets to a Six Flags in Ames from this new sample would most likely be different from the same sample proportion from the old sample due to .a) the central limit theoremb) the law of large numbersc) the population distributiond) sampling variability
