Question

A random sample of 250 attendees of a wine and cheese festival were asked to rate Californian and French wines. Of the 250, 25 rated the wines about equal. Of the remainder, 150 rated Californian wines higher than French wines. At the 3% level of significance, is there evidence to suggest that all wine drinkers rate Californian wines higher than French wines?
