A goodness-of-fit test can be used to determine whether a set of sample data comes from a specific hypothesized population distribution.
 
  Indicate whether the statement is true or false

Question 2

The manager of a fast food store realizes that his staffing problems are a result of the variation in the number of customers that arrive at the store.
 
  If the same number of customers came each hour, she would know exactly how many servers to have working. It turns out that the Poisson distribution works well to describe the arrivals of customers in any given hour. Explain why the manager has more trouble staffing the store during those hours when the average arrival rate is higher.

Answer to Question 1

TRUE

Answer to Question 2

The Poisson distribution has a very special characteristic, the standard deviation is equal to the square root of the mean. Thus, when the mean is small, the standard deviation is also small making it easier to plan. However, in hours where the mean arrival rate is higher, the standard deviation is also higher, thereby causing staffing problems.
