A researcher would like to determine whether people can really tell the difference between the bottled water and tap water. Participants were asked to taste two unlabeled glasses of water, one bottled and one tap, and identify the one they think tastes better. Our of 40 people in the sample, 28 picked the bottled water. Was the bottled water selected significantly more often than would be expected by chance? Use a two-tailed test with α = .05
