The marketing department of Low-Brau, a microbrewery that makes what it considers an excellent light beer, asked 7 volunteers, individually, to taste 3 types of light beer (one of which was the company's brand and the others being competitor brands) and report which one they liked the best. Out of those 7 people, 5 said they liked Low-Brau's light beer the best. The taste test was "blind" in that the volunteers did not know beforehand which of the 3 beers they tasted was Low-Brau's. If there is no difference in the taste of the light beers, what is the chance that 5 out of 7 people would be able to rate Low-Brau's as the best? Hint: This is a binomial distribution problem, and an example of the type of thinking that is required for hypothesis testing, which we'll be going over very soon.
