a coin for 40 times and count the number of tails. The null hypothesis is that the coin is fair and the alternative hypothesis is that the coin is not fair. Please answer whether 6 tails or 18 tails has the smaller p-value and explain why this is so (Hint: when the null hypothesis is true, then we expect to have 20 tails after tossing the coin for 40 times).
