Explanation / Answer

Solution:(1)

Take time to technician to resolve the issue is 18 seconds to 600 seconds

so value of a in minutes

a=18/60 = 0.3 minutes

b= 10 minutes

Solution(2):

Mean time of Uniform distribution can be calculated as follows:

Mean = (a+b)/2

Mean = (0.3 + 10)/2

Mean = 10.3/2 = 5.15 minutes

Solution3:

Variance = (10-0.3)^2 /12

Variance = (9.7)^2 /12

Variance = 7.8408

SD = sqrt(7.8408)

SD = 2.8
