Section1: 
Flip each coin 100 timesNow let’s flip the coins 100 times each, and assume the following results:
Suppose we again think that the coins have the same probability of heads and tails. QuestionCan we now reject the hypothesis that the observed difference between
the coins occurs by Applying Equation (1) to this table yields = 8.333, with one degree of freedom. A table of the distribution shows that there is less than one chance in one hundred of observing such a large difference in the proportion of heads if the same process were governing both coins. ,Handy chisquare and pvalue calculator, developed by Georgetown University
