Concept #1: Probabilities Associated with Sampling Distributions for a Sample Proportion

Concept #2: Probabilities Associated with Sampling Distributions for a Sample Proportion: Intro

Practice: A previous study found that 80% preferred drinking Pepsi over Coca Cola. What is the probability that a random sample of 100 people reveals 60 people or more preferring Pepsi.

Practice: Referring to Practice 1, what is the probability that, from this same random sample of 100 people, that between 10 and 11 people prefer Coca Cola.

Practice: Rihanna and Chris Brown have had some PR issues in the past. A study found that 30% of Americans think that they are a good couple. What is the probability that, out of a sample of 200 randomly selected people, less than 25% consider Rihanna and Chris Brown a good couple?
