A road averages 2,895 vehicles per day with a standard deviation
of 615 vehicles per day. A traffic counter was used on this road on
34 days that were randomly selected.

Demand for Coca Cola at a local restaurant is 60 bottles per day with a standard deviation of 15 bottles per day.
a. Compute the probability that demand will be at most 1700 bottles during the next 28 days.
b. Compute the number of bottles the restaurant should stock to have at most a 9% chance of running out over the next 28 days.
A survey of 170 commuters shows that on average people travel
17.4 km with standard deviation 8.4 km. Find 99% confidence
interval for the population mean commuting distance. State your
conclusion.
Average for a normally distributed demand of a product is 35
units per day. Standard deviation of lead time demand is 10. Lead
time is 3 days. Service level is 95%.
a) Calculate reorder point and safety stock.
b) Reconsider 10 units as daily standard deviation of demand and
re-calculate reorder point.
c) Reconsider that demand is constant, but lead time varies with
a standard deviation of 1 day. Recalculate reorder point.
d) Assume both demand and lead time are...
Problem 2: The average Saturday attendance at a movie theater is
974 people with a standard deviation of 54 people. A random sample
of 39 Saturdays is selected
Part A: What is the probability that a sample mean will be
either less than 954 people or greater than 970 people?
Part B: There is a 97% chance that a sample mean will be above
what attendance level?
Part C: What is the probability that more than 1000 people will
attend...
Problem 1: The average Saturday attendance at a movie theater is
974 people with a standard deviation of 54 people.

The downtime per day for a computing facility has mean 4 hours
and standard deviation 0.9 hour. (a) Suppose that we want to
compute probabilities about the average daily downtime for a period
of 30 days. (i) What assumptions must be true to use the result of
the central limit theorem to obtain a valid approximation for
probabilities about the average daily downtime? (Select all that
apply.) The daily downtimes must have an approximately normal
distribution. The number of daily...
