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:
If the mean cost for each machine is $80, the mean aggregate cost for a sample of 75 machines is:
The mean aggregate maintenance cost is $6,000.
