Question

In a city 15% of the bus riders with a monthly pass are students. In a random sample of 50 bus riders with monthly passes, 12 are students. Find p and p^. I know for p=0.15 but for p^ I have a hard time trying to find.    

Answer 1

p^ is the sample proportion which comes from the data

 

In this case p^ = 12/50 = 0.24
