The annual incomes of 5 vice presidents of TMV industries are $125,000 ; $128,000; $133,000 and $140,000. Consider this a population 
what is the range
range = max-min= 140,000-125,000= 15000
what is the arithmetic mean income?
mean = {125000+128000+133000+140000]/4= 131,500
what is the population variance? the standard deviation? 
Population variance = 5678.908346^2=32250000.00
Population standard deviation=5678.908346...
