Answer 7

A retail store manager wants to find out which brand of T-shirt customers prefer on a given day. There were 150 customers at the store during the day, and he randomly selected 15 customers and asked them their preferred brand.



If he had taken a sample of 30 customers, his predicted value would have been closer to further from the estimated value than the predicted value from the sample of 15 customers.
