Subjects were asked to taste two wine samples in sequence.
Both samples given were the same wine although subjects were expecting to taste two different samples.
Of the 32 subjects in the study, 22 selected the wine presented first when presented with two identical samples.
A) Give a 95% confidence interval for the proportion of subjects who would select the first choice presented.
B) Subjects were recruited in Ontario, Canada via advertisements. What assumption are you making about these subjects?
Please help. I have no clue. Thank you.
