The Soft Landing video game company is about to release a new flight simulator game. If the game is more likely to sell to more than 10% of all video game buyers, the company will make 500,000 copies. If it is less than 10%, the company will make 200,000 copies. Soft Landing sends an e-mails survey to everyone who bought their previous flight simulator game. Of 400 people who responded to the survey, 80 said they were "very likely" to buy the new game. Based on the results of the survey, the Soft Landing company makes 500,000 copies of the game. Was this a good decision? Explain why it is a good decision, or, if not, suggest a better way to gather information.
