Construct a cumulative probability distribution. b. Suppose there are 10 customers to be served. Simulate their service time using the graphical method. 18-20. Aqua-Science Laboratories produces a number of different types of marine science equipment. This company has two different assembly lines to produce its most popular sonar equipment, Aqua-Sonics. The process time for each assembly line is regarded as a random variable and is described by the following probability distribution:

Solution

here p(x<=3) = 0.10,

p(x<=4)= 0.10+0.20 =0.30

p(x<=5)= 0.10+0.20+0.30 = 0.60

p(x<=6)= 0.10+0.20+0.30+0.25 = 0.85

p(X<=x)

8) 1.00

p(x<=8)= 0.10+0.20+0.30+0.25+0.10+0.05 = 1.00

x	p(X<=x)
3	0.10
4	0.30
5	0.60
6	0.85
7	0.95 8) 1.00
