求翻译：There is no set percentage that is accurate for every population. What matters is the actual number or size of the sample, not the percentage of the population. Consider a coin toss: the first few times you flip the coin, the average result may be skewed wildly in one direction (say you got 5 tails in a row), but the m是什么意思？
