Ethical Issue #2

Im a marketing research associate with the Home Depot corporation. Im conducting a focus group in ATL, GA and Im considering using my father as one of the 10 people I need for the focus group because I dont think anyone will find out and he his one year out of the specified age rang I need.
Will I include my father in the group?
I should not and would not include my father in the focus group. Atlanta is a big city so I should be able to find a 10th person for my focus group of people between the ages of 45-55. Putting my father in the focus group could cause him to answer some questions in ways he feels would benefit me instead of answering the questions truthfully and thus he would be contributing to faulty and misleading conclusions from this focus group. I would also have to lie to the Home Depot corporation which means I would'nt be keeping an open relationship with them and ultimately I would be presenting them with research that is not a true representaion of what people between the ages of 45-55 in ATL, GA are thinking which could lead Home Depot to do something wrong and lose them a lot of money.
