Ice Cream Narrative
A supermarket chain has its own house brand of ice cream. The general manager claims that her ice cream is better than the ice cream sold by a well-known ice cream parlour chain. To test the claim, 40 individuals are randomly selected to participate in the following experiment. Each respondent is given the two brands of ice cream to taste (without any identification) and asked to judge which one is better. Suppose that 25 people judge the ice cream parlour brand as better, 4 say that the brands taste the same, and the rest claim that the supermarket brand is better.
-Refer to Ice Cream Narrative. Can we conclude at the 1% significance level that the general managers' claim is false? Justify your answer.
