1. Clark Property Management is responsible for the maintenance , rental and dayto-day operation of a large apartement complex on the east side of New Orleans.
George Clark is especially concern about the cost projections for replacing air
conditioner compressors. He e would like to simulate the number of compressor
failures each years over the next 20 years. Using data from similar apartement
building he manages in a New Orleans suburb, Clark establis a table of relative
frequency failures during a year as shown in the following table :
NUMBER OF AC
COMPRESSOR FAILURES
0
1
2
3
4
5
6
PROBABILITY
( RELATIVE FREQUENSI)
0.06
0.13
0.25
0.28
0.20
0.07
0.01
He decided to simulated the 20-year period. Select the random numbers. Conduct the
simulation for Clark. Is it common to have three or more consecutive years of
operation with two or fewer compressor failures per year ?
2. The number of cars arriving per hour at Lundberg’s Car Wash during the past 200
hours of operation is observed to be the following :
NUMBER OF CAR
ARRIVING
3 or less
4
5
6
7
8
9 or more
FREQUENSI
0
20
30
50
60
40
0
a) Set up a probability and cummulative probability distribution for the variabel of
car arrivals.
b) Establish random number interval for variable.
c) Simulate 15 hours of car arrivals and compute the average number of arrivals per
hour.
