SCENARIO 8-11
A poll was conducted by the marketing department of a video game
company to determine the popularity of a new game that was targeted
to be launched in three months. Telephone interviews with 1,500
young adults were conducted which revealed that 49% said they would
purchase the new game. The margin of error was ±3 percentage
points.
Referring to Scenario 8-11, what is the needed sample size to
obtain a 90% confidence interval estimate of the percentage of the
targeted young adults who will purchase the new game by allowing
the same level of margin of error?
