Question

Answer 1

This senecio is in reliable because how do you know if the people at the sand which shop next door are frequant customers

Answer 2

Answer:

This sampling method is not representative of the entire Rewards customers.

Step-by-step explanation:

To know if frequent customers prefer Sony or Fuji cameras, you have to sample within the frequent customers' population. People from the sandwich shop next door are not necessarily frequent customers in Best Buy.

I would send a questionary to all frequent customers through email with the question "What branch of cameras do you prefer?" Or if is only between Sony of Fuji, then the question would be "What branch of cameras do you prefer, Sony or Fuji?" Not all frequent customers will answer, but you will get better representativeness of the frequent customers' population.
