In order to increase revenue many video game publishers sell

In order to increase revenue, many video game publishers sell downloadable content (DLC) separately from the main game. Such content could include additional costumes for the playable characters, additional online game modes, special weapons, etc. A recent industry survey policed 927 game players ages 20 to 30 asking them how important DLC was to their enjoyment of a game. In that sample, 516 people reported that DLC was \"very important\' to the m. Suppose that the company conducting the survey wants to test the hypothesis that the true population proportion of game players who believe DLC is \"very important\" is 0.5. Calculate the value of the test statistic to two decimal places.

Solution

Test statistic z = (p-0.5)/(p(1-p)/927) where p = 516/927 = 3.471
