Answer the following discussion questions:

1. What is the probability of more than 3 phone calls per hour?

2. With current staffing plans, the bakery could handle up to 6 phone calls per hour during its busiest periods. What is the probability of more than 6 phone calls during one of the busy hours of the day? Is this a concern?

3. Where do we encounter Binomial or Poisson processes in everyday life?

4. Are there any tools in Excel to help us work with Binomial or Poisson distributions?

5. In what areas of your daily lives are normal curves used to describe things?

HINT: Remember - to find the probability of more than 3 calls you will need to use the concept of complimentary events, i.e. probability of more than 3 would be P(X>3) = 1 - P(X<=3).
