My classmates and I are doing a coin toss experiment (i.e. toss coin 100 times). I have already determined that I have a fair coin, since I tossed $43$ heads, and this falls into a $95$% confidence interval of $40-60$ heads.
Now, I am to assume that everyone in my class, and including myself, have a fair coin (i.e. $p=0.5$). How do I determine whether everyone in the class will find that they do in fact have a fair coin, based on their calculations? I think that most people will find that their experiment will support the fact they do have a fair coin. However, I also think there has to be some who will not. How do I determine what percentage of the class conclude that they have a fair coin?
There are 20 people in the class.
