T determine what people like to do in their leisure time, the customers os a music store are surveyed. Of these, 85% said that they like to listen to music, so the store manager concludes that most people like to listen to music during their leisure time. Does the manager make a valid conclusion? Explain your answer.
If you ask people at a football game if they like to watch football, is that a fair sample or should you stop people at random on the street?
If it's a fair sample wouldn't you ask people at a football game if they like to watch football? If you just ask random people on the street it would be a random sample wouldn't it?
Asking customers at a music store if they like music says is not a valid way to find out if "most people" like music. People who do not like to listen to music are not likely to be in the music store.
