Problem 1 [4 pts]: The maintenance cost of machines are uniformly distributed from 0 to 160 (dollars). If a random sample of 75

Andru [333]

Answer:

$6,000

Step-by-step explanation:

The mean value of a sample is assumed to be the same as the mean of the population. The mean of a uniformly distributed variable between 0 and 160 is:

$M = \frac{0+160}{2}\\ M=\$80$

If the mean cost for each machine is $80, the mean aggregate cost for a sample of 75 machines is:

$M_{75}=75*\$80\\M_{75}=\$6,000$

The mean aggregate maintenance cost is $6,000.
