Suppose in conducting hypothesis testing to test the fairness of a coin using significance level alpha=0.01, we use a sample of 100 coin flips and we observed a certain number of tails.
Then we use the probability distribution of number of tails for a fair coin in 100 coin flips, and we see that according to this probability distribution, the probability of occurrence of what we observed is 0.002, that is, considerably less than the significance level.
Which can be stated based on these observations?
Group of answer choices
a.) It proves that the fair is definitely unfair
b.) observed evidence does not support the fairness assumption under this significance level, but there is still a chance that the observed results would occur even for a fair coin
