If we flipped a coin 100 times, we expect “heads” to come up about 50 times if the coin is “fair”. In a study of probability, it can be shown that the number of heads hthat appears in such an experiment must satisfy the given inequality,|h-50/5|<1.645 , to be considered “fair”. (a) Solve this inequality for h.(b) If you flipped a coin 100 times and obtained 40 heads, is the coin “fair”.
