Suppose 20% of the people in a city prefer Pepsi Cola as their soft drink of choice. If a random sample of six people is chosen the number of Pepsi drinkers could range from Zero to six. Shown here are the possible numbers of pepsi drinkers in a sample of six people and the probability of that number Pepsi drinkers occurring in the sample. Use the data to determine the mean number of Pepsi drinkers in a sample of six people in the city and compute the standard deviation.
