Question

For each of the four variables Total Income, Monthly Payment, Utilities, and Debt, see the attached sample means. If each of these is used as an estimate from the corresponding (unknown) population mean, is there any reason to believe that they either underestimate or overestimate the corresponding population means? Why or why not?

The means are calculated from a total of 500 random selected samples from a population of 1,000,000.
