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 polled 700 game players ages 20 to 30 asking them how important DLC was to their enjoyment of a game. In that sample, 580 people reported that DLC was "very important" to them.
Suppose that the company conducting the survey wants to see if the true population proportion of game players who believe DLC is "very important" is greater than 0.80. Calculate the p-value of the test of this hypothesis, to three decimal places.
