A pollster wants to know the average income of those who supported John McCain for president. He asks 100 supporters and calculates a mean of​ $67,543. Is this mean x overbar   or mu ​?   A. mu ​, because it is calculated based off data from the entire population..   B. x overbar ​, because it is calculated based off data from the entire population.   C. mu ​, because it is calculated based off data from a sample.   D. x overbar ​, because it is calculated based off data from a sample.
