14.2 Campbell’s Soup Company is going to produce a new flavor for their soup product. They conducted a survey to ask users to vote on their favorite soup flavor. It found that 40% voted for creamy seafood, 35% voted for tom yam chicken, and the remaining voted for herbal chicken. Campbell’s invited 150 testers to a soup testing campaign and found that 75 preferred creamy seafood, 30 preferred tom yam chicken, and the rest preferred herbal chicken. Based on the data, can Campbell’s conclude that the preferences in the survey are the same when compared with the campaign at the 5% level?
