Companies pay large amounts of money to make sure their Web sites are highly ranked on Google. Advanced Web Ranking reported that if your Web site is the very first search result on Google, desktop users will click on that result 34% of the time (this is called a click-through rate). Suppose that a certain company asks its Web manager to report the company's click-through rate. He conducts a random sample of 567 users and reports a click-through rate of 45%. Does this sample give the company reason to believe its results are working better than usual? Or could this just be a lucky result?
