A poll surveyed 341 video gamers, and 85 of them said that they prefer playing games on a console, rather than a computer or hand-held device. An executive at a game console manufacturing company claims that less than 26% of gamers prefer consoles. Does the poll provide convincing evidence that the claim is true? Use the a= .10 level of significance with the p-value method and Excel. Compute the test statistic. Do not round intermediate steps. Round the answer to two decimal places.
