c. Find the probability an individual sample mean is less than 7.9 customers per hour.
d. What is the distribution of the underlying population (customer arrivals)?
e. Use the standard error to calculate an approximation for the underlying population standard deviation. Is this calculation consistent with your understanding of the distribution of the underlying population? Why?
