You can  put this solution on YOUR website! 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... 
Cheers,
