WebOct 8, 2024 · Step 1: Establish normality. We need to make sure that the sampling distribution of the sample mean is normal. Since our sample size is greater than or equal … WebProperly, the sampling distribution APPROXIMATES a normal distribution for a sufficiently large sample (sometimes cited as n > 30). A coin flip is not normally distributed, it is either heads or tails. But 30 coin flips will give you a binomial distribution that looks reasonably normal (at least in the middle).
