   Question

   Suppose 80% of people think that milk chocolate tastes better than dark chocolate. Is the sampling distribution (of the sample proportion of people that think milk chocolate tastes better) normally distributed if we would have samples of n = 200?

   
   
   1. FALSE: Yes, because n is bigger than 30.
   2. FALSE: Yes, because n is bigger than 15.
   3. TRUE: Yes , because  np > 15 and n(1-p) > 15.
   4. FALSE: No, because np is not bigger than 30.
   
   

   Solution

   The right answer is: Yes , because  np > 15 and  n(1-p) > 15.
