Some of the stock in a winery has been found to be infected by Brettanomyces. A winemaker independently sample 80 barrels from the winery, and find that 28 of them are infected. Suppose that, unbeknownst to her, one quarter of the barrels in the winery are truly infected. She carries out a hypothesis test to evaluate the claim that half of the wine barrels are infected. What is closest to the p-value that she obtains? 0.0024 0.0051 0.0097 0.35
