When we doing the hypotheses, we have two assumptions: one is the sample must be independent ; one is meeting the CLT.
But why? is it related to the normal distribution?

How can you find the probability for your sample proportions? This would be extremely difficult to work out without CLT because CLT uses the mean of this distribution and this mean relates to a normal distribution, which enables us to find the probability very easily.
