Out of the 80 customers surveyed, 65 of them liked the IPhone the most. If 500 people were given the same survey, predict how many would prefer an IPhone?

Respuesta :

406 would be expected to prefer the iPhone.

Based on the survey, the probability that someone would prefer an iPhone is 65/80.  Multiplying this probability by 500, we have

65/80(500) = 406.25 ≈ 406.
