Single Blind Taste Test Experiment

The goal of this experiment is to see if more college students prefer Diet Coke or a bargain brand Diet Coke. A single blind taste test was given to everyone in the class to determine which soda they like better. A Bernoulli distribution was used to determine which brand was conducted to each participant first. This process insures that the samples given to the subjects are random as possible and to cut any bias. The participants were given the two random samples and were asked to tell which was liked better. The results of this test were recorded then analyzed. From the data, the statistic of people who preferred the Bargain brand was 6/20. This means that the majority of the subjects preferred the real Coke brand over the Bargain brand. A hypothesis test was conducted to test the hypothesis that Diet Coke and a Bargain brand coke are equally

The materials needed to conduct this experiment included 3 to 4 cans of store brand diet coke and name brand Diet Coke, a sharpie, small Dixie cups, and cardboard trifold. The experiment was set up as a single blind experiment. The administrators knew what Dixie cups contained the name brand coke and what Dixie cups contained the store brand, while the taste testers did not. First, the store brand and the name brand had to be assigned either Z or Y using the Bernoulli distribution. To make sure the assignments were random a computer generator was used through the stat crunch program. The Bernoulli parameter used for this Bernoulli distribution was 0.5. This means that there is an equally likely chance of getting a 0 or a 1 as a result. If the result was 0 the bargain brand would be called Y and the name brand would be called Z. If the result was 1, the bargain brand would be called Z and the name brand would be called Y. This made sure that the participants did not know which coke they were
