Suppose you didn’t know whether the coin was fair or not and you wanted to determine a 95% Confidence interval for the actual probability of obtaining a head. If you flipped the coin 16,000 times and obtained exactly 8040 heads, your 95% confidence interval would range approximately from: (a) 0.4992 to 0.5208 (b) 0.4892 to 0.5318 (c) 0.4948 to 0.5102 (d) 0.5002 to 0.5198 (e) 0.5262 to 0.5448
