I have some questions:

A researcher wants to determine the mean income of adults in a particular state. She decides to tae a random sample of 1525 citizens with a driver's license. Which of the foollowing statements is not correct?

A) People without a license will be missed in the sample

B0 People from another state wil not be included

C) The mean income of the sample will be reasonably close to the mean of the population

D)It is likely that most people of driving age will be included.

E) The sample standard deviation will be simolar in value to the actual standard deviation.

I think that C is the right answer. Is it correct?

Thank you
