A vending machine dispenses hot chocolate or coffee. Service
time is 35 seconds per cup and is constant. Customers arrive at a
mean rate of 61 per hour, and this rate is
Poisson-distributed.
a. Determine the average number of customers
waiting in line. (Round your answer to 2 decimal
places.)
Average number of customer
b. Determine the average time customers spend in
the system. (Do not round intermediate calculations. Round
your answer to 2 decimal places.)
Average time
minutes
c. Determine the average number of customers in
the system. (Do not round intermediate
calculations. Round your answer to 2 decimal
places.)

A vending machine dispenses coffee. The average cup of coffee is
supposed to contain 7.0 ounces. Eight cups of coffee from this
machine show the average content to be 7.3 ounces with a standard
deviation of 0.5 ounce. Using a 5% level of significance, test
whether the machine has slipped out of adjustment and if the
average amount of coffee per cup is different from 7 ounces.

A machine in the student lounge dispenses coffee. The average
cup of coffee is supposed to contain 7.0 ounces. A random sample of
eleven cups of coffee from this machine show the average content to
be 7.2 ounces with a standard deviation of 0.50 ounce. Do you think
that the machine has slipped out of adjustment and that the average
amount of coffee per cup is different from 7 ounces? Use a 5% level

A machine in the student lounge dispenses coffee. The average
cup of coffee is supposed to contain 7.0 ounces. A random sample of
six cups of coffee from this machine show the average content to be
7.3 ounces with a standard deviation of 0.40 ounce. Do you think
that the machine has slipped out of adjustment and that the average
amount of coffee per cup is different from 7 ounces? Use a 5% level

A coffee machine dispenses 6 fluid ounces of coffee into a
paper cup. Previous studies have shown that the amount dispensed is
a normal distribution. A random sample of 15 cups is obtained where
the standard deviation, s, is 0.154.
Determine if the requirements are met to compute a confidence
interval for the true standard deviation, σ, of amounts of coffee
being dispensed. List each requirement and state information given
to support each one.
If the requirements are met, use...

A soft drink vending machine dispenses cans of drinks at the
JKUAT cafeteria. The machine waits for students and/or staff to
insert coins. All soft drinks cost KShs. 50 and the machine can
only accept Ten, Twenty and Forty shilling coins. A customer must
insert a total of fifty shillings for the machine to dispense
drinks.
